A New Approach to Sample Mineralization in an Open System for the Analysis of Geological Samples by Inductively Coupled Plasma Mass Spectrometry with Improved Performance Characteristics

We developed and tested a high-performance system for the acid mineralization of silicate samples in open vessels of original design with programmable heat treatment conditions. A formalized description of operations in the procedures of the acid mineralization of various silicate samples (ultrabasic, basic, and acidic) is proposed, both on a quantitative and a descriptive level. Problems of ensuring the accuracy of the analysis of geological samples by inductively coupled plasma mass spectrometry are discussed.
