A method for the determination of 40 elements in geochemical samples and coal fly ash is described. Pulverized samples are mixed with sulfur powder and specimens are prepared in the form of pressed disks. In addition to acting as a binder, the sulfur matrix dominates the absorption properties of the specimen disks. Thus, matrix absorption corrections can be determined for a single specimen and applied to the analysis of a wide class of samples. Standardization is achieved using nebulized multielement solution deposits, as well as two single element vacuum vapor deposited thin-film standards. Utilizing two 25-min analysis periods, results achieved are typically accurate to within +- 5% when x-ray counting statistics are not the limiting factor.
