Lancek Valued Member United States 442 Posts	Posted 02/28/2021 10:22 am I know there are meters that can test for gold. But I've heard that they don't work for silver. How about platinum? Is there any way to test to see if something is platinum, and if so, how pure? Report this Post to the Staff

sbr Valued Member Canada 128 Posts	Posted 02/28/2021 4:02 pm I sold some palladium a little bit ago and the buyers machine was able to check the purity. The same machine checked gold and platinum .I don't know for sure but I think it also tested silver. Report this Post to the Staff
sel_69l Bedrock of the Community Australia 21788 Posts	Posted 02/28/2021 4:49 pm XRF is OK for testing the surface down to a depth of only 5 microns. Beware, however. Pt an W are of approximately the same density, so XRF testing inconclusive for Pt plated W. W = Wolfram, otherwise known as tungsten. Report this Post to the Staff

XRF = X-Ray Florescence is an entirely different investigative technique. A bullion dealer is very likely to have an XRF hand held instrument. Report this Post to the Staff
