On Features and Possibilities of Direct Integrated-Scintillation Emission Spectral Analysis of Powder Samples with Their Evaporation from Electrode Crater

摘要

By example of investigating an artificial sample and ash of a sorbent (active granular carbon) on which noble metals from the solution of a geological exploration sample are deposited, features of the inte-grated-scintillation method of analysis of powder samples with their evaporation from an electrode crater are considered. Generation of shorter scintillation fractional analytical signals with relatively large amplitude under selected conditions of the analysis allows the enhancement of the sensitivity and accuracy of the powder sample analysis. The technique is implemented with an element detection limit of 0.01- 0.001 g/t.
