New isotope dilution results are presented for Rb and Sr concentrations in U.S.G.S. standard rocks and NBS-70a K-feldspar. The results (based on at least five analyses of each rock), are generally accurate to -+ 0.5% and resolve discrepancies in previously published data. X-ray fluorescence analyses
Microgram quantities of arsenic are determined in geological materials or water samples by copreclpitating the analyte with elemental selenium and using x-ray fluorescence directly on the precipitate. The coprecipitation step removes elemental interferences and converts the sample to a thin film. Th
