    Chapter 1:

    Do You Really Know that Gold Is Real?

    Not many people believe that gold is real. You cannot blame them for their belief because there are many pieces of fake or counterfeited gold in the market. This has been the case for centuries. Since the real gold is more expensive and valuable than the fake one, you must pay serious attention to the type of gold you are buying or using.

    1.1, The Karat gold

    The K gold has a high degree of pure gold in it. This indicates that after refining a piece of gold, the impurities have already been removed. This can be achieved by using some gold-cleaning chemicals such as borax and soda ash.

    They are usually added to the molten metal (gold) while it is still hot; this helps to separate the pure gold from other metals that can be described as precious or less precious metals. Gold can also be purified through the use of gold-melting furnaces.

    Gold purity is measured in Karatage, which indicates the percentage of gold purity. When compared with other metals, it is very important to know how much pure gold is present in a particular gold material (for example, a jewelry or gold wristwatch) when compared with another alloy.

    The higher the Karatage of your jewelry, the larger the amount or proportion of pure gold in it.

    1.2, Different gold Karatage

    As indicated below, the higher the number of gold Karatage, the larger the quantity of pure gold in the material.

    24 Karats = 100 percent gold (it simply means a 24 Karat gold necklace, for instance, is made of 100% of pure gold)
    22 Karats = 91.75 percent gold
    21 Karats = 87.5 percent gold
    18 Karats = 75 percent gold
    14 Karats = 58.5 percent gold
    12 Karats = 50.25 percent gold
    10 Karats = 42 percent gold
    9 Karats = 37.8 percent gold
    8 Karats = 33. 75 percent gold

    1.3, The dangers and economic losses of impure gold

    Using a large amount of impure gold to make jewelry has some disadvantages. Pay attention to the following points described below:

    I. Economic losses:

    Gold jewelry or coins made from low Karatage gold are generally cheap to buy. For example, a genuine 1 oz gold coil may cost a little over $1000.

    But you may get a counterfeit gold coin in the market a lot less than that, maybe around $700 or $850. Do you know what?

    Even though it is cheaper than the original gold coin, you have just wasted your $700 or $850 buying a counterfeit gold coin you don’t need or cannot sell for a better value.

    Imagine the amount of economic losses you will sustain if you pack your gold bullion full of hundreds or thousands of low-Karatage gold coins!

    This is why it is very important to know how to detect counterfeit gold materials and save yourself from wasting your scarce resources on buying them.

    II. II. Bad reputation in business:

    If you are running a jewelry business and mistakenly use counterfeit gold for the production of your jewelry, your business may lose it good reputation if your customers eventually detect that your jewelry are made from low-Karatage gold. Your business operations may be affected in the following ways:

    1. Pure Gold Processing plant: You may experience these problems when unknowingly using gold with very low Karatage to produce your jewelry:
      • Color failure: Counterfeit gold may be able to give a product a temporary golden look or appearance. However, such a sheen or shining feature cannot last for a long time.This is because no plating material can possess the same color and endurance qualities of gold. In no time, the color will begin to peel off and eventually show the original color of the metals used instead of the genuine gold.
      • Not passing quality standard tests: Despite efforts by counterfeiters to make impure gold look like the real thing, it is impossible for counterfeit gold to pass the quality standard tests required for gold jewelry production. This means that the low-Karatage gold you mistakenly bought and used will result in a massive waste of your capital.
      • Technical problems associated with gold jewelry production: There are going to be some technical issues if the producer skips or ignores doing the required standard quality tests and continues with jewelry production.It is a fact that the differences in density between the actual gold and the counterfeit product will affect mold volume calculations. This will result in mismatched sizes and volumes.Since the melting point of the impure gold is different from that of the genuine gold, there are going to be problems when the impure raw gold is fed into a gold jewelry vacuum casting machine.This may cause either under-heating or over-heating of the counterfeit gold material. The jewelry vacuum casting machine only works perfectly with the genuine gold melting point or temperature.
    2. K gold processing plant: You can also run into some problems while processing K gold if you are using (intentionally or unintentionally) some low-Karatage gold. Though the issues you have to deal with are similar to that associated with the processing of pure gold, but with slight differences.
      • Color failure: The impure K gold seriously has a color issue because its shining appearance will fade within months or even weeks! And no buyer would be happy to see their expensive “gold jewelry” lose its sheen after two months.It is observed that this fading coloration occurs when low-Karatage gold is used in the gold jewelry vacuum coating machine for the production of jewelry. As you can see, this outcome is absolutely undesirable.And the owner of the jewelry business will find himself/herself in a big problem with his/her customers.
      • Quality Issues: Real (or original) gold products possess good qualities such as high durability and ability to withstand stress and pressure.Counterfeit gold jewelries are made from non-gold metals which do not necessarily have the same shining appearance as genuine gold. And they also have poor quality when compared with the jewelries made from genuine gold.Hence, this apparent lack of durability makes them bend, break, and can have a scratch easily. The counterfeit gold products are not also strong enough to withstand pressure and stress.
    3. Lost Wax Casting:Pay attention to this: When impure gold is used for lost wax casting, modelling and polishing, you will have to struggle with some technical issues.These include having minor issues like a “sand hole” appearing on the products. The sand hole occurs due to a certain discontinuity in the layer of “counterfeit gold” that was used for the lost wax casting.Though, it is possible to repair this minor problem, but it shows that low-Karatage gold is not as good as the genuine one with 100 percent gold.Other serious concerns are that the sand hole may lead to some other irreparable problems such as grit or Fujin. The only way to handle such a mess is to completely scrap the impure gold products.

      As it turns out, that is a complete waste of resources—all the money spent on acquiring impure gold often ends up being a wasteful spending! You need to discard them immediately if you want to retain your business’ good brand or reputation.

    Chapter 2:

    Why Do You Need A Professional Gold Analyzer?

    You need a professional gold gold testing machine so that you will be able to test gold purity and also identify impure gold.

    Because if you fail to do so, you and your jewelry business will face some of the problems described in Chapter One. Some of these problems include:

    • Loss of money: The money you spent on buying impure gold is nothing but a waste.
    • Bad business image: Selling counterfeit gold coins or jewelry to your customers will ruin your business reputation once your customers discovered that you have been deceiving them with impure gold products.
    • Poor-quality gold products: Since they are made of counterfeit gold, your jewelry will not pass most of the standardized quality tests.
    • Color issues: Some other precious metals used instead of genuine gold in counterfeit gold jewelry do not possess similar shining color of gold. Even though some of them may shine brightly at first, but they will soon lose their sheen because they are not durable—they cannot stand the stress and pressure that the genuine gold can withstand.

    If you are very careful about saving your business, you will do everything you can to have a professional gold analyzer and save yourself and business from irredeemable destruction that may arise by mistakenly selling impure gold products to your customers.

    If you need some simple methods to identify fake gold, click here to see some simple ways to test fake gold

    2.1, Impure gold types that cannot be identified by simple methods

    There are some impure gold types that cannot be easily identified using some or all of the simple methods highlighted above. This is because the precious metals used as the base materials have properties or qualities that resemble that of gold.

    It is totally confusing to gold shop owners and pawnshop owners to differentiate between jewelries made from the pure gold and Tungsten that has layers of pure gold on it. As a matter of fact, Tungsten jewelries are somehow brighter than some gold jewelry. And when tested with some simple methods, it may be difficult to confidently say that it wasn’t a pure gold jewelry.

    Other precious metals that can stand in the place of pure gold are copper, which is indeed brighter than gold in color when polished. Precious metals such as palladium, platinum, and zinc can also be used. But when they are cut in cross-sections, you can detect their colors.

    So, jewelries made from Tungsten and Copper are the most confusing to gold shop owners and pawnshop owners.

    2.2, An introduction to gold analyzers

    Advanced gold purity machines produce better results of separating fake gold from genuine gold. Highlighted below are some examples of modern gold-analyzing technologies:

    I.Melting and Sampling spectrum detection:

    The concept behind this test is that melting and sampling spectrum detection utilizes a thermo-analytical method referred to as Differential Scanning Calorimeter. It is a more rigorous and expensive test, but it produces much better results than simple methods.

    All you need to do is to place a sample of the gold to be analyzed in a Differential Scanning Calorimeter alongside a reference gold sample. This requires the same temperature intensity being applied to both the sample and the reference gold materials.

    Hence, you will need to record the difference in the amount of heat needed to increase the temperature of the sample when compared with the reference material. You will be able to easily detect which of the two gold materials is genuine based on this heat difference.

    II. Metallographic Analysis:

    Every precious metal has its unique metalogical properties. So, based on this assumption, it is possible to use this technique to separate counterfeit gold from the genuine one.

    All you are expected to do is to conduct some metallographic analyses that will assist you in identifying impure gold. This entails using microscopy. And the two typical types of microscopy in use are optical microscopy and scanning electron microscopy with energy-dispersive x-ray analysis (SEM/EDX).

    Since the properties of real gold through microscopy are already known to person doing the test, they can use that knowledge to separate pure gold from an impure one.

    III. Smelting Identification:

    If you use this technique, you can obtain clear results that differential a pure gold material from a fake one. Smelting, as you know, indicates that you will need to melt an ore or alloy of various elements in order to separate the base elements or metals of interest from the other constituents of the alloy.

    You can carry out the smelting using a machine such as Superbmelt gold melting equipment that supplies very high heat which is hot enough to melt the ore or alloy. After smelting the ore or alloy of the material to be tested, you can prove the originality of gold it melts out first.

    Other metals such as copper and zinc with different melting temperatures or points will melt later, and this can indicate the availability of impure gold.


    IV. Fire Assay: People have been using this technique since the ancient times. The good news is that it is still as effective as it was many years before. Using Fire assay, you will evaluate the gold content in a sample by melting it in a furnace.

    You will need to carefully measure its weight all along the process. The molten gold is then poured into a kind of crucible known as a cupel. This will be further heated to allow other impure metals to leave the crucible, leaving the gold alone.

    You will then need to cool down the remaining gold and weigh it to determine the amount of the sample which is actually gold.

    V. Atomic Absorption Spectroscopy (AAS):

    In chemistry laboratory, AAS is commonly used to do spectro-analytical evaluation of the components of an element. This technology (AAS) works via the principle of absorption of optical radiation.

    This follows the assumption that different elements have varying ways of interacting with light. In essence, some elements are better absorbers of light than the others. more. According to literature, gold has the maximum light absorption at wavelengths 400nm and 320nm in the violet and nearby ultra-violet regions of the spectrum respectively.

    So, if an AAS test reveals results varying too widely from the pure gold standards, that will be a proof that what you are dealing with is fake gold. Atomic Absorption Spectrometers can either be medium range Line source AAS or high range Continuum Source AAS.

    VI. Inductively Coupled Plasma Mass Spectrometry (ICP):

    You can use this kind of spectrometry to detect a fake gold material from an original one. Unlike AAS, you can use a very small sample for ICP. This is another form of spectrometry which is similar but different from AAS.

    All you need to do is to ionize the sample with an inductively coupled plasma. You will then use mass spectrometry to separate and measure the ions in the ionized sample. Through this technique, you can also measure the percentage composition of pure gold in a given sample.

    Finally, you will need to compare the amount of gold obtained from the ICP-MS test with the specified amount. This can help you determine whether the gold is genuine or not.

    VII. X-RAY Fluorescence (XRF): Out of all the different types of advanced methods of identifying impure and pure gold, XRF is the most complicated but the easiest to operate.

    XRF functions by emitting a beam of X-ray photon which hits the atom of the sample to be analyzed. After the collision with the x-ray photon, electrons of different elements release varying amounts of energy.

    Therefore, specific elements like gold can be readily observed considering the energy released by its electron. You can easily spot a counterfeit gold material because they will definitely give off different amounts of energy, revealing their counterfeiting nature. XRF technique is fast and the XRF spectrometer is highly portable.

    Chapter 3:

    What Are the Gold Testing Machines in the Market?

    There are different types of gold analyzers in the market. They range from the acid gold-testing kits to portable gold-testers and sophisticated gold-testing equipment. It is important to state that each tester has its own usefulness or capabilities.

    However, at the industrial or commercial level, sophisticated gold-testing tools or equipment like gold spectrometer and XRF gold analyzer are utilized.

    3.1, Gold Spectrometer

    Gold spectrometer comes in different forms and they carry out different functions. As a matter of fact, there are two distinct types of spectrometers that can be used to identify whether a certain piece of gold is genuine or fake. These include:

    • Optical spectrometer: This spectrometer reveals the intensity of light as a function of wavelength or frequency. When a ray of light passes through a noble metal, for example, it emerges as a spectrum (band) of lights or lines that can be studied to reveal the actual composition of that particular metal.So, if a ray of light passes through a genuine piece of gold, it produces some distinct lines that are different from when the same ray passes through a fake piece of gold. In the case of fake gold, its components will produce a band of lines that are obviously different from those obtainable from the real gold.

      How optical spectrometer works, picture obtained from CCC Maker

    • Mass Spectrometer:This kind of spectrometer estimates the amount of certain substance in a mixture (compound) using the concept of mass-to-charge ratio and the quantity of the gas-phase ions. In other words, it is a fact that even pure gold consists of gold and other noble elements in small proportions.And fake gold, on the other hand, has very little amount of gold but containing large amounts of other metals. So, using a mass spectrometer, it is possible to estimate the percentage (amount) of purity a piece of gold is.There are two types of mass spectrometer: You can either choose to use a magnetic spectrometer or a time-of-flight spectrometer. The principle behind a magnetic spectrometer is that when a charged particle (a piece of gold, genuine or fake) passes through a constant magnetic field at right angles, it moves in a circle based on its charged property and mass. Real gold will produce different circular path of radius from fake gold.

      How Mass Spectrometer works, picture obtained from ResearchGate

    In general, spectrometers depends largely on the following properties of noble metals: Wavelengths, or frequencies, or masses, and these properties are useful for separating genuine gold from their fake counterparts through the actions of light or magnetic intensity.

    3.2, XRF gold analyzer

    XRF gold testing machine is a very popular tool for analyzing gold purity within a short period of it. Over the years its precision and reliability has increased. Today, you can even use XRF Gold Analyzer to determine the Karat of your gold. The good news is that such an analysis can be completed between 3 and 10 seconds.

    There are different kinds of XRF Gold Analyzers, but the most common one is the handheld XRF Gold Tester.

    You need a handheld XRF Gold Analyzer if you are a gold refiner, recycler, or analytical assay researcher. As the amount of fake gold objects that are flooding the market increases, it becomes imperative that gold storeowners and pawnshop owners invest in buying an XRF Gold Analyzer.

    Here are some benefits you can derive from using this very useful tool (XRF Gold Analyzer):

    • It provides 100 percent non-destructive analysis, in the sense that it will not affect the quality of the gold during analysis
    • It is portable and can be easily conveyed from one location to another
    • It is fast and accurate—you can obtain the analysis results in as little as 5 seconds
    • It doesn’t require elaborate trainings before you can use it
    • It can be used to detect pure gold in all types of gold compounds (substances), such as gold jewelry, gold bars, gold pins, gold ore, gold plating, alloys with gold content, gold nuggets, and yellow, white, and rose gold

    3.3, Comparisons of these gold analyzers

    There are many kinds of gold measuring equipment on the market, and you need to know roughly each one, such as gold measuring kit (chemical method), hand-held gold measuring instrument, and desktop gold measuring instrument.

    The desktop gold measuring instruments are placed on the desks and can be operated manually or with an automation. The table below shows the comparisons between the three forms of gold-measuring equipment:

      3. What is used for Initialization?Initialization is used to adjust the peak to 0. It likes a scale. When we use scale, we need adjust to 0 firstly, then we can weigh any goods.As every element has its characteristic spectrum, its difference of every spectrum will show different position on X-axis of the software. So, we need fix a reference spectrum to 0, then other elements spectrum position will be fixed. At here, we set Au spectrum at 0. Then software will know where Cu spectrum is and where Ag spectrum is, and so on.Initialization is an automatic process to adjust Au peak to 0. If Au peak not at 0, machine will show wrong report.
      4. What jewelries could do the Initialization?Software requires to use pure gold for initialization.
      5. How often could we do the calibration?Calibration is not necessary and needn’t doing often. Calibration is only done when the testing results are inaccurate. Calibration should be done by professional staffs.
      6. What are standard samples?Standard samples are used for calibration to build up the working curve.
      7. What is the solution if the results are not satisfactory?XRA2000 is based on advanced technology of XRF (X-ray Fluorescence). The testing error is below ±0.3%.When the testing results are not satisfactory: First, check the peak of Au. If the peak is far away from 0, perform an initialization. Secondly, check the sample’s placement to see if it is put on the right place on the testing window. Thirdly, check the jewelry samples.As explained above, XRA2000 could analyze well-proportioned samples. If the samples are not flat and inhomogeneous, you need to polish the surface of the jewelry samples to analyze.
      8. Could XRA2000 analyze plating jewelry? XRA2000 could analyze plating jewelry. The plating surface should not be too thick due to the penetration of X-ray. For different element thicknesses, ranging from 5-15 microns, we can also adjust the machine according to requirements.

    The Applications of the Superbmelt XRF Gold Analyzer

    This section describes, in detail, how Superbmelt XRF Gold Analyzer can be applied when it comes to analyzing gold purity. Chapter Four has revealed all the important information concerning the features and parameters of Superbmelt XRF Gold Testing Machine.

    So, how do you apply the equipment great qualities in testing your gold purity and doing other associated functions? You will get all the necessary answers from this chapter.

    5.1, How to apply the Superbmelt XRF gold analyzer

    It must be stated that Superbmelt XRF Gold Analyzer cannot directly determine the purity of gold by merely testing a point on its surface.

    Why not? There are some jewelries that are coated or platted with some other materials or precious elements. In that case, testing a particular point on their surfaces will not yield a correct estimation or calculation of gold purity.

    There are two unique approaches that can be utilized in testing gold purity in the scenario described above.

        • Melting gold before detection: In gold standard laboratory, it is important that a pure piece of gold is used. Therefore, a testing must be carried out to determine gold purity.In order to be sure that you are properly using Superbmelt XRF Gold Analyzer to test the purity of your gold or gold materials (jewelries, bangles, necklaces, trinkets, and so on), the first you have to do is to obtain the gold in the craft or jewelry in its purest form or state.How will you do this? You will have to, first of all, melt the gold in the craft or jewelry using any good gold-melting machine or furnace. After this process, you can then take a sample from the melted gold to test it purity using Superbmelt XRF Gold Analyzer.
        • Four cross-sectional testing:A jewelry store recycles gold jewelry but worries about the purity of gold in the jewelry. In this case, it is advisable that gold purity should be tested.Another useful method you can use to test the purity of your gold while applying Superbmelt XRF Gold Analyzer is to undergo four cross-sectional testing.What does this mean? It indicates that rather than testing the purity of gold from a point on the surface of the craft or jewelry, you will need to first cut the jewelry in four equal cross-sections.Take the four cross-sections and then test the purity of gold in them on Superbmelt XRF Gold Analyzer. You should take the average value of the four testing results to determine the approximate gold quality percentage.

          You can also drill the gold in order to test its purity. The gold particles that come of the drills can be tested for purity.

    NOTE: The underlying principle behind all XRF Gold Analyzers is that they cannot penetrate gold to detect internal purity. In that case, efforts must be made to reach the gold itself, and the two methods described above are the best practices to achieve this.

    5.2, Some factors influencing the efficiency of Superbmelt gold analyzer

    It is not enough to only know the main principle behind Superbmelt XRF Gold Analyzer, you must also understand some important factors that can influence getting a correct estimate on gold purity. Pay attention to these essential processes while using Superbmelt XRF Gold Analyzer:

    1. Use a gold-melting machine that can obtain gold samples in their purest forms
    2. Equally cut the coated or plated gold jewelry in four equal sections so that you can get accurate average result for your gold purity
    3. Strictly follow the manufacturer’s instructions when using the XRF Gold Analyzer
    4. Keep the gold-testing machine in the most suitable environment so that its functions will not be affected by any external factors
    5.

    Frequently Asked Questions

    How many elements can the XRA2000 analyzer analysis?

    XRA2000 can give quantitative analysis of Au, Ag, Pd, Pt, Cu. Zn and Ni will calculate in Cu. It can qualitative analyze Fe,Co,Zr,Mo,Zn,Ni,Ru,Rh,Cd,Os,Ir,w,etc., exceed 20 elements.

    What is the time setting for analysis?

    According to XRF technology, longer time realize better result. Usually we set 120 seconds for analysis. You could decide the testing time following based on your experience.

    What is the initialization used for?

    Initialization is used to adjust the peak value to 0. It is the same as the scale. When we use the scale, we need to adjust to 0 first, then we can weigh any weight of the goods. Since each element has its signature, each spectrum will show a different position on the X-axis of the software. So we need to fix the reference spectrum to 0, then the spectral position of the other elements will be fixed. Here, we set the Au spectrum to 0. Then the software will know where the Cu spectrum is and where the Ag spectrum is, and so on. Initialization is a process of automatically adjusting the Au peak value to zero. If the Au peak is not 0, the machine will display an incorrect report.

    What jewelries could do the Initialization?

    Software requires to use pure gold for initialization.

    How often do we do calibration?

    Calibration is not required and does not need to be done often. Calibration is only performed if the test results are inaccurate.

    What are standard samples?

    Standard samples are used for calibration to build up the working curve.

    What is the solution if the results are not satisfactory?

    The XRA2000 is an advanced technology based on XRF (x-ray fluorescence) with a test error of less than ±0.3%. When the test results are not satisfactory: First, check the peak of Au. If the peak distance is 0, initialization is performed. Second, check the placement of the sample to see if it is in the correct position of the test window. Third, check the jewelry samples. As mentioned above, the XRA2000 can analyze well-sampled samples. If the sample is uneven and uneven, you need to polish the surface of the jewelry sample.

    Could XRA2000 analyze plating jewelry?

    XRA2000 could analyze plating jewelry. The plating surface should not be too thick due to the penetration of X-ray. For different element thicknesses, ranging from 5-15 microns, we can also adjust the machine to test different thickness according to requirements.

    How long should we warm up the machine at the beginning of using every day?

    We suggest 15-30 minutes for warming up every day.

    Is your machine accurate?

    There is no doubt that our machines are accurate. But it has a lot to do with the sample itself. The tester must ensure that the sample is not plated or otherwise chemically pickled. If the sample is small, you can polish it. If the sample is large, you can flatten it, or cut it, and then test its parts.

    How long is your warranty?

    Our warranty is one year. Light could hold 5 years warranty. Usually customer use the machine for many years with no quality problems.

    What kinds of precious metals can your machine test?

    Our machine can test solid, liquid and powder precious metals.

    Will your X-Ray analyzer harm to body health.

    Certainly not. The X-Ray is weak and we design protecting function. If you open the chamber cover carelessly when the power is operating, the machine will switch off the X-Ray automatically.

    Can machine test the fake gold?

    As we know, the XRF analyzer is testing the point of the material surface to read gold purity. There are two quickest ways to avoid fake gold inside when you buy from market. 1st way is to melt and mix it evenly with induction melting furnace. Then use our gold analyzer to test the purity. 2nd way is to drill different parts of the material like four corners, middle and back for machine analyzing. It could avoid to buy fake gold well.

    Can it detect the exact percentage of the gold? Like 18kg is 75% gold?

    Yes, our gold analyzer could test the gold percentage in your material. It will show Au, Ag, Pd and Cu (other metals will add in Cu element). The machine equips with one printer to print the report to show customer.
