Over the last few years, there has been a significant increase in the use of portable X-ray fluorescence throughout the business. Initially developed for alloy and scrap metal identification, the technology was eventually shown to be successful in environmental field monitoring, notably contaminated land and remedial operations. The application of portable XRF in soil research has pushed the growth of mineral prospecting. And, as a result of continuous advancements in XRF technology, XRF is now more responsive and accurate; these advancements have altered the way scientists perform real-time in situ and field research.

Can a portable XRF detector be used to test the purity of gold?

The flame test method is the most often used method for detecting gold content. A flame melts the metal, and the concentration of gold or other metal components is determined. For a long time, the flame method was thought to be the most effective approach to detect gold. However, such detecting procedures are damaging and unfavorable to pawn shops.

When we developed the Handheld XRF Gold Analyzer, we analyzed six large flat objects made of different grades and compositions of gold, and we found that the accuracy was typically within 0.1% or 0.2% of the flame analysis results. The experiment concludes that TrueX Gold can completely test the composition of items with high accuracy.

We tested the Handheld XRF Gold Analyzer on six large flat objects made of various gold grades and compositions and discovered that the accuracy was often within 0.1% or 0.2% of the flame analysis results. The trial concludes that TrueX Gold can accurately test the composition of objects.

Advantages of portable XRF for gold detection

X-ray fluorescence analysis technology (XRF)'s intelligent non-destructive testing tool can precisely detect the concentration of various elements in gold, platinum, palladium, K gold, K platinum, and other jewelry. Multi-channel analyzers are used in the EXF series precious metal detectors, while spectrum analysis technology is used to accurately and vividly present the content and ratio of gold, platinum, palladium, silver, rhodium, copper, zinc, nickel, and many other elements in jewelry in the form of a spectrum.

Can X-ray fluorescence fully replace gold flame detection?

It is indisputable that X-ray fluorescence may not only examine the validity of gold, but also, and most crucially, analyze its exact purity. The purity of the gold is frequently what impacts the pawnshop's income. The X-ray fluorescence is an effective method for identifying gold, although it cannot detect heavy plating or counterfeiting. As a result, we strongly advise utilizing X-ray fluorescence as a secondary test to guarantee that there is no thick coating or counterfeiting.
