XRF Gold Analyzer Buying Guide
A professional handheld XRF analyzer is a high-tech analysis solution designed to meet the tough challenges of a rapidly evolving industrial sector. The professional handheld XRF analyzer helps to streamline costs, minimize risk and increase production efficiency.
The handheld XRF spectrometer provides high performance in-field testing instruments delivering materials and coating analysis that adds value to the production lifecycle from material exploration to incoming inspection, production and quality control.
1.1, Do you really know that Precious Metals are Real?
Precious metals are real and to detect the originality of a precious metal, a handheld XRF analyzer is needed. Precious metals are valuable, therefore making jeweller or other manufacturers to mix metals and other materials to fake the appearance of gold, silver, platinum or palladium.
Gold plating and counterfeit items are just some of the challenges that jeweller, gold traders and pawn shop owners face on a daily basis. Businesses require accurate results to remove variability and subjectivity from determining item value to ensure a profitable transaction.
The handheld XRF analyzer accurately determines the content of gold and all precious metals such as silver, platinum and palladium in materials. For precious metal analysis, such as jewelry or dental alloys, fast and nondestructive handheld XRF analyzers which require little sample preparation are most frequently used for analysis of precious metals.
1.2, Make coins by manually pressed or “struck”
Chemical assay, fire assay and other alternative methods of testing precious metals seem increasingly out of date in the 21st century. The handheld XRF analyzer puts the state of the art metal testing method into your hands.
Precious metals are today of interest for jewelry, industrial use, and investment. With the handheld XRF analyzer, materials can be detected and tested for content and purity with extreme cases.
Detecting the authenticity of precious metals can be done in a number of ways. The most common methods are:
Naked eye or using a jeweller’s loupe- An experienced jeweler can verify the authenticity and quality of some jewelry by looking at it under magnification. This method is not always accurate.
Weight/density measurement- Gold is a dense metal, the idea behind this test that if you drop a gold piece in water and measure how much liquid it displaces, you can determine whether it is pure gold. However, gold is often alloyed with other metals in legitimate jewelry, making this test unreliable.
Markings- Gold jewelry sometimes has identifying marks that indicate its purity, such as 24k or 20k, but these can be faked.
Nitric acid- A piece of gold is scratched against a testing slab to leave a mark. Nitric acid is applied to the mark to see whether it will dissolve. Depending on the acid’s concentration, the purity of the gold can be determined. This method however causes damages to precious metals.
XRF analysis method is a completely nondestructive method, XRF analysis leaves the jewelry intact and undamaged. The portable XRF analyzer sends x-rays into the jewelry, exciting the atoms and causing them to fluoresce energy back to the analyzer’s detector. This tool uses fluorescence x-rays to determine the jewelry’s material chemistry.
With the use of the Silicon Drift Detector (SDD), it is used for fire assay analysis of precious metals. Fire assay determines precious metal content by measuring weight loss after removing base metals through cupellation. Handheld XRF analyzer on the other hand uses x-ray fluorescence to excite the sample and calculate returning characteristic x-rays.
A skilled operator of fire assay can produce results that are accurate up to 0.035%. This process takes time and most times results often differ when testing is done several times.
Anyone above the age of 18 can be taught how to operate the handheld XRF analyzer in less than an hour.
For speedy and accurate evaluation of precious metals, handheld XRF is the tool of choice.
1.3, Identify and Avoid Fake Precious Metals
Handheld XRF analyzer works accurately when it comes to analyzing precious metal swiftly, precisely, easily and non-destructively. This is a tremendous value to all precious metal specialists, recyclers, refiners, miners, bulk jewelry producers, etc.
Given today’s high value for precious metals, many jewelry stores have become involved in the purchase of old jewelry and scrap jewelry. Using a handheld XRF analyzer, it is possible to determine the content of the item offered for sale and its karat value in less than a minute.
The handheld XRF analyzer can identify karats and percentage of gold and percentage of silver, platinum and palladium in less than 5 seconds as well as perform a complete analysis in less than 10 seconds. Since the handheld XRF displays the value to one hundredth of a decimal point, you will not only be able to identify if the precious material you are buying is below karat, you will also be able to identify by exactly how much.
This non-destructive method can analyze gold (Au), silver (Ag), Platinum (Pt), Palladium (Pd) and many more precious metal and base metal alloys: karat gold, low grade gold, gold plated, gold plated, silver grades, platinum alloys.
Using handheld XRF analyzers to test and analyze precious metals encompasses a multitude of advantages. Precious metals are not exposed to harsh chemicals during testing and analysis.
X-Ray Fluorescence (XRF) is a common investigative technique capable of providing qualitative and quantitative data on the composition of a chemical sample. XRF analyzers are based on the principle that atoms absorb energy from the X-rays, become momentarily excited and then give off secondary X-rays.
There are two major types of Energy Dispersive (ED) XRF analyzers available in the market; handheld and desktop configurations.
2.1, Desktop XRF Analyzer
The desktop XRF analyzer is also known as a benchtop XRF analyzer. They are capable of simple element identification and qualification up to more sophisticated analysis. Desktop XRF analyzers generally provide higher sensitivity and resolution as well as a wider elemental range because they utilize more powerful x-ray sources. The more x-rays going in, the more fluorescent x-rays coming out.
The desktop XRF analyzer is easy to operate, compact and x-ray safe instruments without a need for additional chemicals or operating gasses.
When looking at the benefits of desktop XRF analyzer, a major benefit is the user free operation when a programmable stage is included in the system. This functionality allows the user to measure multiple points per sample and/or multiple samples per run without manually setting up each measurement.
This offers great efficiency to organizations because the XRF operator can set samples up and return later.
Additional benefits of the desktop XRF analyzers include the multiple collimators, mapping functions and the versatility that they offer in specific applications.
All the features and benefits offered by the desktop XRF analyzer make them the best fit for most coating thickness measurement interests. The component configuration allows the desktop system to measure more than single layer coatings. Other features of the desktop XRF analyzer include; flexible configurations, latest software development that makes the XRF analyzer easy to use, power efficiency, fast and sensitive.
The desktop XRF analyzer is widely used in a variety of industries and applications, even when light element analysis is of utmost importance. The desktop XRF analyzer is used for the following applications: Cement production, mining, mineral beneficiation, petroleum and petrochemicals, polymers and related industries, glass production, forensics, pharmaceuticals, healthcare products, environmental, food and cosmetics.
2.2, Handheld XRF Analyzer
Handheld XRF analyzer is also known as portable XRF gun. Handheld XRF analyzers offer the ability to analyze materials on site or in the field, without having to take samples back to the lab. The handheld XRF analyzer looks somewhat like an electric drill or pistol. This handheld analyzer for instance can be used by geologists, who might wish to perform on-site material analysis, or facilities managers, who might want to access the metallurgy of steel pipe welds.
The greatest benefit of the handheld XRF analyzer is the portability, that is the small size it provides, this allows the handheld XRF analyzer to be easily transported for immediate use and on-site analysis. The inbuilt XRF analyzer battery is capable of lasting for several hours of analysis on work sites.
While beneficial in many applications this is highlighted in mining related applications when quick decisions save time and money. In addition to this, the handheld material analyzer does not require that samples fit in a chamber so they are excellent in situations with large sample pieces such as weld analysis of large pipes, alloy analysis in aerospace applications, scrap recycling, etc.
The handheld XRF analyzer application fields include: Mining and exploration, precious metal alloy, iron and steel smelting, waste metal recycling, machinery manufacturing and recycling, boiler pressure vessel, aerospace industry, ship building, scrap sorting, jewelry making, archeology, etc.
There may be a price overlap between the handheld XRF analyzer and the desktop XRF analyzer, most handheld configurations have the benefit of low cost acquisition.
How the handheld XRF analyzer differs from the desktop XRF analyzer:
When you need a quick measurement- Aiming the portable XRF gun to the test materials and getting the result within a few seconds is the go to option.
Flexibility- Whichever sample you want to analyze, liquid, plastic, minerals, powder or big rocks, the handheld XRF gun is always ready to analyze on the go.
Indication- The handheld XRF machine delivers quality results while being fully able to cope with mobility requirements, automatically correcting for ambient temperature and pressure fluctuations. With the handheld XRF analyzer, users can easily select materials without any calibration.
Mobility and long lasting battery power- Handheld XRF analyzers can be carried around with an inbuilt battery which allows you to analyze for many hours in the field. The desktop XRF analyzer on the other hand does not have an inbuilt battery, the XRF analyzer has to be connected to a power source. The desktop XRF analyzer is more suitable for stationary element analysis rather than moving from one work site to another. It is mostly used in laboratories, offices, jewelry stores, etc.
2.3, Modern Techniques of Identifying Original Gold
Recently the originality of gold and other precious metals can be detected by any of these techniques: Fire assay, Atomic Absorption Spectroscopy (AAS), Desktop analyzer and Handheld XRF analyzer. All these techniques are designed to analyze the elemental composition of precious metal.

XRF refers to x-ray fluorescence spectroscopy. XRF is a nondestructive analytical technique used to determine the elemental composition of materials. Superbmelt handheld XRF analyzer works by measuring the fluorescent or secondary x-rays emitted from a sample when excited by a primary x-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent x-rays. These x-rays are different for each element, therefore making the handheld XRF analyzer an excellent tool for qualitative and quantitative analysis.
Step by step XRF analysis:
- X-rays are produced by the analyzer and pointed at a sample surface.
- The energy causes the inner-shell electrons to be ejected.
- Outer-shell electrons fill the vacancies left by the ejected electrons and fluorescent x-rays are emitted.
- The fluorescent x-rays enter the detector and send electronic pulses to the preamp.
- The preamp amplifies the signals and sends them to the Digital Signal Processor (DSP).
- The DSP collects and digitizes the x-ray events and sends the spectral data to the main CPU for processing.
- The CPU analyzes the spectral data to produce detailed composition analysis.
- Composition data and other grade or value identification are displayed and stored in memory for later recall or download to an external PC.
3.1, The Principle of Superbmelt Handheld XRF Analyzer
Superbmelt handheld XRFspectrometer is based on the principle that individual atoms when excited by an internal source energy, emit x-ray photons of a characteristic energy or wavelength. By counting the number of photons of each energy emitted from a sample, the elements present in a material are identified and quantified.
Here is a detailed breakdown of the process:
An x-ray beam with enough energy to affect the electrons in the inner shells of the atoms in a sample material is created by an x-ray tube inside the handheld XRF analyzer. The x-ray beam is then emitted from the front end of the handheld XRF analyzer.
The x-ray beam then interacts with the atoms in the sample material by displacing electrons from the inner orbital shells of the atom.
This displacement occurs as a result of the difference in energy between the primary x-ray beam emitted from the XRF analyzer and the binding energy that holds electrons in their proper orbits; this displacement occurs when the x-ray beam energy is higher than the binding energy of the electrons with which it interacts. Electrons are fixed at specific energies in their positions in an atom, and this determines their orbits. In addition to this, the spacing between the orbital shells of an atom is unique to the atoms of each element, so an atom of potassium (K) has different spacing between its electron shells than an atom of gold (Au), or silver (Ag), etc.
When electrons are knocked out of their orbit, they leave behind vacancies, making the atom unstable. The atom must immediately correct the instability by filling the vacancies that the displaced electrons left behind. Those vacancies can be filled from higher orbits that move down to a lower orbit where a vacancy exists. For example, if an electron is displaced from the innermost shell of the atom (that is, the one closest to the nucleus), an electron from the next shell up can move down to fill the vacancy- this is fluorescence.
Electrons have higher binding energies the further they are from the nucleus of the atom. Therefore, an electron loses some energy when it drops from a higher electron shell to an electron shell closer to the nucleus. The amount of energy lost is equivalent to the difference in energy between the two electron shells, which is determined by the distance between them. The distance between the two orbital shells is unique to each element, as mentioned above.
The energy lost can be used to identify the element from which it emanates, because the amount of energy lost in the fluorescence process is unique to each element. The individual fluorescent energies detected are specific to the elements that are present in the sample material. In order to determine the quantity of each element present, the proportion in which the individual energies appear can be calculated by the handheld XRF spectrometer.
The entire fluorescence process occurs in small factions of a second. A measurement using this process and a modern handheld XRF gun can be made in a matter of seconds.

Before buying a handheld XRF analyzer, there are certain points you should consider what you want to achieve. For instance, if you are looking to confirm the quality of precious metals for your jewelry company or to confirm alloy grades for incoming goods, you will want to know the important element in those grades. Dangerous equipment failures, excessive downtime, loss of profit and ruined reputation are some of the implications manufacturers who do not verify the materials coming into the plant or leaving the plant in the form of finished products face.
The most common question when purchasing a handheld XRF analyzer is that involving the handheld XRF price. The handheld XRF price varies due to the fact that different applications require different calibrations and hardware. A handheld XRF analyzer that is calibrated for light elements in alloys requires a faster, more sensitive detector than an XRF calibrated for basic alloys where light elements are not a concern.
It is clear that the XRF analyzer cost is driven by the actual needs of the customer. Regardless of the XRF analyzer price, the amount saved over traditional analysis far outweighs the initial upfront cost.
Handheld XRF analyzers are mostly required in a busy and harsh working environment. There can be sharp edges on manufacturing machinery or produced parts, broken and torn metal throughout the recycling facility and lots of sharp edges on fasteners, screws and bolts on pipelines. These handheld XRF analyzers are also used in environments that contain excess dirt, dust and moisture.
If you are investing in the handheld XRF analyzer, then you should make sure it is rugged and reliable. So before purchasing, make sure they are durable, but that your operators handle them with care. Look for these features that make the handheld XRF analyzer durable: Detector protection, IP54 certified, lightweight but tough, ergonomically designed. In addition to the weight of the analyzer, the design is also important. If it is difficult to handle, it could slip from hand when in use.

How accurate is an XRF gun?
XRF analysis provides a fast, accurate and most importantly a nondestructive method to test the purity and composition of metals, alloys, geochemical materials, etc. Generally, heavier elements are slightly more accurate than lighter ones. Accuracy in the range 0.1 to 100% is higher than the range of 1ppm to 1000ppm. Accuracy is generally better for metals than for minerals and plastics. Accuracy will also be better if a powder sample has low particle size or if a massive test sample is flat. The accuracy of the difference between XRF value and assay can be as good as 0.2 to 0.5% for gold in jewelry. Accuracy can also be improved by adjusting the response of the instrument for a given type of material using reference samples. There are additional reasons to use XRF analyzers and not chemicals like nitric acid when it comes to analyzing precious metals such as jewelry. The traditional acid test for gold involves placing a small drop of strong acid onto the metal’s surface. This type of testing could leave a mark on the jewelry which is dangerous to the skin. Acid testing is not accurate and does not give the exact karat in gold testing.
Are XRF guns safe to use?
Handheld XRF guns are totally safe to use when operated as directed. An XRF tool produces x-rays that are ionizing radiation, therefore exposure should be minimized. Do not place your hands when analyzing material. Do not point the handheld XRF gun at anyone and pull the trigger due to the effect of radiation.
Can XRF detect sodium?
Sodium is the lightest element capable of being detected by the XRF analyzer.
Can XRF detect gold?
The handheld XRF analyzer can detect gold, silver and other types of precious metals.
Can XRF detect aluminium?
Aluminum alloys fall into the category of light metal alloys and can be detected with a XRF analyzer.
How does an XRF gun work?
XRF is an acronym for x-ray fluorescence, a process whereby electrons are displaced from their atomic orbital positions, releasing a burst of energy that is characteristic of a specific element. This release of energy is then registered by the detector in the XRF instrument, which in turn categorizes the energies by element. The XRF gun works in this four simple processes; Emission- First, the analyzer emits x-rays Excitation- The x-ray hits the sample, causing it to fluoresce and send x-rays back to the analyzer. Measurement- The detector measures the energy spectrum. This tells you which elements are present and the amount of each element present. It is important to note that the Superbmelt XRF analyzer can measure every element between 12 to 92 atomic numbers on the periodic table. In general, our analyzers can measure magnesium to uranium on the periodic table of elements. The results of the assay is displayed on the in-built LCD. Typical results will display a table listing all elements that the analyzer detected, as well as the concentration of each element.
What is the principle of XRF?
XRF is based on the principle that individual atoms, when excited by an external energy source, emit x-ray photons of a characteristic energy or wavelength measuring 100A to 0.1A. By counting the number of photons of each energy emitted from a sample, the elements present may be identified and quantified. Compared to normal electromagnetic waves, x-rays easily pass through substances and become stronger as the atomic number of a substance through which it passes decreases. X-ray fluorescence analysis is a method that uses characteristic x-rays generated when x-rays irradiate a substance.
Is XRF a surface technique?
XRF is an elemental analysis technique that can quantify many elements in a sample. The characteristic x-ray photons produced in the sample have specific energy and on the way to the detector get absorbed by other atoms in the sample. The information depth depends on the energy of the element of interest and the type of sample (the average atomic number). This depth ranges from one micrometer to a few centimeters.
Why can XRF detect light elements?
XRF analyzers can detect light elements because they have energy levels that are low enough that they struggle to escape from the sample without being absorbed. For fluorescent x-rays that do escape the sample, some of them will not be able to penetrate the air between the sample and the instrument to reach the detector. There have been certain improvements in portable XRF technology that enables the detection of light elements like magnesium. Light elements previously cannot be measured because their signal is too weak to estimate their concentration. The silicon drift detectors allow for more energy in total to be received and measured by the portable XRF analyzer, improving detection limits and the number of lighter elements that can be measured.
What is an XRF instrument?
A handheld XRF spectrometer is an x-ray instrument used for routine and relatively fast, nondestructive chemical analysis of rocks, minerals, sediments and fluids. XRF instruments can provide information about elements present in almost any solid sample and in many cases, provide quantitative elemental composition information of every material.
How does XRF measure thickness?
Coating thickness measurement instruments are available for metal manufacturing. XRF is a nondestructive analytical technique that measures the fluorescent x-ray emitted from a sample when it is excited by a primary x-ray source. The strength of the signal can be used to determine the thickness of the coating, a second reading can determine the thickness of the substrate. The intensity of the fluorescent x-ray corresponds to the number of x-rays detected per unit of time, which is known as count rate. This count rate is related to the thickness of the material being tested.
What are the purity ranges of gold jewelry?
The most common gold purity levels are 10k, 14k, 18k and 24k. Each level of gold purity has its advantages and disadvantages, from strength and durability to the risk of skin irritation. Out of the four most common purity levels, 10k is the most durable with the lowest gold content. 14k is slightly purer while also highly durable, while 18k gold is the purest form of gold used for jewelry. 24k gold pure gold, it is soft and malleable. Gold and it’s alloys are 375, 585, 750, 916, 990 and 999.
What are the purity ranges of silver jewelry?
The silver purity levels are: 99.9% (999 thousandths) , 92.5% (925 thousandths), 83.5% (835 thousandths) and 80% (800 thousandths). 925 silver is also known as sterling silver, it is the most common alloy used in the manufacture of silver jewelry and other fine silver items. Silver and its alloys are 800, 925, 990 and 999.
What are the purity ranges of platinum jewelry?
Platinum jewelry is either 90% (900 Pt) or 95% (950 Pt) pure platinum. Platinum is a naturally durable yet malleable material. Platinum needs to be mixed with only a small amount of other platinum group metals to create an alloy that can be molded. Platinum and its alloys are 850, 900, 950, 990 and 999.
What are the purity ranges of palladium jewelry?
Similar to platinum, palladium is used as an alloy of 95% or 950 purity. Palladium is considered a hypoallergenic metal. Palladium and its alloys are 500, 950, 990 and 999.

What are the characteristics of X-ray fluorescence spectroscopy?
The x-ray fluorescence spectroscopy is characterized by: fast analysis; highly accurate and precise analysis; nondestructive analysis of materials, solid, liquid and powder materials; ease of use, etc.
What is the working principle of XRF equipment?
The sample specimen is excited by radiation of an x-ray. This causes electrons from the inner electron shell to get knocked off. Electrons from outer electron shells drop in to fill the resultant voids emitting a fluorescence radiation characteristic in its energy distribution for a particular element. The fluorescence radiation is measured by the detector.
