Method for the emission analysis of the elemental composition of liquid media

摘要

The method relates to the field of applied physics, more particularly to spectral methods for determining the elemental composition of liquid media. In the emission analysis method for determining the elemental composition of liquid media, first the elements that are to be determined are deposited in the space of a diaphragm opening under a current that is not of sufficient magnitude for the localization of electrical discharge, and then the direction of the current is altered and the magnitude thereof is increased to initiate the localization of electrical discharge. The radiation occurring in the liquid under analysis is recorded to obtain the emission spectra of the chemical elements that are to be determined. The result is an increase in the stability and reproducibility of measurements.
