I brought in 400 grams of pt/pd sponge, a test sample of 4 grams pd salt, and a 25ml sample of chloroplatinic acid to a Gold Buyer. He tested the sample of salt and it was 950 purity. He then tested the bulk of the material and said it only had traces of pgms.
How is it possible to lose the pgms in the process of calcining? Bear in mind that I used a propane torch and the smoke was white only.
Is it possible that they can't properly test calcined material?
