Fischer's X-ray fluorescence (XRF) instrument is the most popular brand in alloy analysis of precious metals, material analysis of fashion jewelry, and quality control of high end watches.
Buying and selling physical gold and other precious metals always carries risk. There is a possibility that the gold does not contain the amount of carats it says it has or contains other metals within. Thus, it is important to be able to eliminate this risk with measurement instruments you can trust.
Fischer has decades of experience in manufacturing highly accurate and precise instruments to measure gold non-destructively. These instruments are able to measure alloy concentrations in percentages (or carats) or use electrical conductivity to check if other materials are present inside the gold. Using Fischer instruments ensures that you are able to authenticate the piece of gold you are buying or selling.
