Hi!,
Steven jones has already had the samples analysed by an independent lab with XRD, and the analysis was inconclusive, dont waste any money on XRD… And you haft to describe exactly how the material/matrix looks, the size of the particles, everything, and what you want to find out, and you cant trust all the recommendations you will get for this very small samples, you haft to ask around and get a second opinion. Just some advice so that you dont waste your money!.
Best regards
Andre
