XRF Analysis of Rocks and Minerals for Major and Trace Elements on a Single Low Dilution Li-tetraborate Fused Bead

Abstract

The precision and accuracy of a low (2: 1) Li-tetraborate tised bead technique by X-ray fluorescence analysis for 27 major and trace elements is demonstrated by comparison to accepted values of standard samples and to values acquired by other techniques in other laboratories. The increased efficiency of using a single bead for major and trace elements is achieved without loss of precision or accuracy and the beads may be stored for tens of years without degradation.
