In my lab we test recycled precious metals. When the samples come to the lab they are in powder form. We use fire assay fusion and cupelation to determine material content (precious metals). We do use peroxide fusion with ICP-OES finish to get preliminary numbers so we can determine the proper flux mix for each sample.
My question is: when it comes to this material, what is more accurate fusion/collection or titration? Our samples have different matrix and the silver content ranges from very high to very low (80+% to 0.01%)
