XRF Gold Testing Machine

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.

1.1, Do You Really Know That Precious Metals are Real?

Now that there are more and more kinds of gold jewelry and other precious metal products on the market, it is no longer possible to know their authenticity, purity, content, etc. by simple observation and touch. Therefore, professional experimental methods or instruments must be used to achieve accurate evaluation.

So what are the ways to verify gold now?

Fire Assay

Fire assay is a method used to determine the purity and content of precious metals, such as gold and silver. It involves the use of high temperatures to melt and separate the metal from the ore or sample being tested.

People have been using this technique since the ancient times. 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.

Smelting

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.

X-RAY Fluorescence

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 technology works by emitting a beam of X-ray photons, which then strike sample atoms. The two interact, and electrons of different elements release different amounts of energy to analyze their elements.

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 he doesn’t need to damage the metal, at the same time the XRF spectrometer is highly portable.

1.2, Benefits of SuperbMelt Gold Testing Machine

Some of the great benefits of using Superbmelt gold analyzer are that it gives users:

Accuracy

XRF gold testers are highly accurate and provide precise readings of the purity and composition of the metal being tested.Superbmelt gold testing machine have accuracy in  0.03-0.1%, and the accuracy can be selected according to the application requirements.

Non-destructive

XRF gold testing machine are non-destructive, meaning that they do not damage or alter the piece of metal being tested. This is particularly important for jewelry, where the integrity and value of the piece may be affected if it is damaged during testing.

Speed

XRF gold testers provide fast and efficient results, allowing for quick and easy analysis of multiple items in a short amount of time.The measurement time of our gold detector is 3-120 seconds, which can meet the simple verification requirements in a short time, and the longer detection time can also display all the metals contained in the metal sample at the same time.

Portability

We have developed a hand-held gold meter specially for outdoor and gold buyers, etc. The machine is compact and portable. XRF gold testers are relatively small and portable, making them easy to transport and use in a variety of settings.

Cost-effective

Compared with other traditional gold detection equipment, the price of the xrf gold testing machine may be relatively high, but for long-term use, it is the most cost-effective, and it can well solve the gold authenticity and purity detection in most industries. And it does not need to buy too many expensive accessories and chemical reagents, it can be put into work directly after assembly, which is simple and convenient.

Versatility

In addition to the most basic gold detection, we can realize the detection of 5-80 kinds of elements, which can be applied to most precious metal industries, such as jewelry, precious metal laboratories, banks, precious metal refining industries, etc. XRF gold testers can be used to test a variety of precious metals, including gold, silver, platinum, and palladium.

1.3, Comparison between SuperbMelt Gold Testing Machine and Fire Test

When compared with fire assay, the Superbmelt XRF Analyzer comes with some advantages over this method.

Let’s see what’s the difference between these two methods：

Principle

XRF testing is a non-destructive analytical technique that uses X-rays to determine the elemental composition of a material, including gold. Fire assay, on the other hand, is a destructive method that involves melting the gold sample and separating the precious metals from impurities.

Speed

XRF testing is typically faster than fire assay. XRF can provide results within seconds, whereas fire assay can take several hours or even days.

Cost

XRF testing is usually less expensive than fire assay because it requires less equipment and fewer chemicals. Fire assay is a more complex and time-consuming process that requires a range of specialized equipment and chemicals.

Sample Size

XRF testing requires a small sample size, usually less than a gram, whereas fire assay requires a larger sample size, typically between 10 and 50 grams.

Application

Fire assay gold is more suitable for refineries, ore purification and metallurgical industries, where precious metals are separated from other components by smelting.

This also determines that it is smart to work in a fixed scene. The xrf gold testing machine is easy to transport and can realize changes in usage scenarios. It is more suitable for some gold buyers and the jewelry industry.
