Hi Digby, Just a hunch that it is sampling problem. When dealing with course gold particles a representative sample size is rarely practical. Without knowledge of gold particle size and sub-sample/analyte mass it is hard to make this judgement.
As you point out, the sub-sample values should have a normal distribution. Increasing the number of samples (n) would help. Eight samples is unlikely to be enough to characterise what is probably a highly variable distribution. Regards David Reid
