Ken,
John D. is quite right about the importance of including a blank standard.
I'm looking for a good pyrite blank too - i.e. known very low concentrations of trace elements, perhaps by LA-ICP-MS.
Also, watch out for microinclusions in the pyrites. Some of the trace elements tend to concentrate there.
