There are many ways to test chemical compositions, such as bench spectrometers, handheld spectrometers, chemical analyses, energy spectrums, etc. We commonly use a handheld spectrometer because it is a non-destructive test that is convenient and fast.
Before testing, we need to ensure that the product is machined and wipe the surface with alcohol to remove metal residues.
A handheld spectrometer must have all the channels that you need. For example, the main content of cobalt alloy is cobalt. If there is no cobalt channel, Cobalt will be distributed proportionally to other ingredients when you measure cobalt products. Then, you will get the wrong result.
