XRF Determination of 19 Trace Elements In International Geochemical Reference Samples

Abstract
Routine XRF determination of 19 trace elements in 23 international standards using the method of Leake et al is examined. Agreement of results for 15 well‐established international reference samples is generally good, showing that this method gives comparable results to other techniques. New trace element data using this method are presented for the 8 USGS III standards.
