Abstract
A method in which samples are mixed with CuO and graphite in the proportions 1920 has been tested on a wide variety of non-metallics using an ARL Quantometer The technique yields results accurate within a factor of 1.2 for a majority of determinations ranging from traces (0 01% level) to major constituents. When applied to one class of material, bauxites of different origins having varied mineral structures, the method gives much improved accuracy without evidence of appreciable matrix effects. Advantages and limitations of direct-reading instrumentation for semi-quantitative analysis are presented
