Status of and perspectives on microwave and glow discharges for spectrochemical analysis. Plenary lecture

Abstract

Glow discharge atomic emission and atomic fluorescence and microwave plasma atomic emission spectrometric methods are reviewed and compared with the conventional atomic approaches of electrothermal atomization atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry, and inductively coupled plasma mass spectrometry. Diagnostical characteristics and analytical figures of merit are given for a number of plasma types and spectrometric methods, respectively. Theoretical efficiencies of detection and measurement are given for the glow discharge and microwave plasma methods. Quantitation methods are discussed and future predictions of a number of atomic spectrometric methods are given in tabular form.
