  • Method for quantitative analysis of chemical composition of inorganic material
    Patent number: 4365969
    Abstract: A method for quantitative analysis of the chemical composition of an inorganic material comprising extraction of the element being determined from a sample of the inorganic material into the gas phase by treating the sample with a reagent that forms, with the element being determined, a volatile halide that is quantitatively analyzed in the gas phase. The method of this invention enables the determination of a broad range of elements. It is possible to determine one, two and more elements in a single experiment. The method is highly sensitive. The lower limit of detection of elements is 10.sup.-5 to 10.sup.-7 %. The accuracy of determination of elements present in concentrations of 10.sup.-5 to 10.sup.-6 % ranges from 15 to 30%.
