Glass Reference Standards for Trace Element Analysis of Geologic Materials
Five glass standards were prepared for quality control of the trace element analysis of rocks. One standard is a blank, and the other four each contain 46 added elements at uniform concentration levels aimed at 500, 50, 5, and 0.5 ppm, respectively. The blank represents the matrix composition approximating an average igneous rock. Preliminary evaluation spectrochemically of the trace element content and homogeneity of these glasses has demonstrated their usefulness as reference standards.
