PLASMA SPECTROCHEMICAL ANALYSIS METHOD AND PLASMA SPECTROCHEMICAL ANALYZER

摘要

The present invention provides a plasma spectrochemical analysis method that can be carried out easily and can achieve high analytical sensitivity The plasma spectrochemical analysis method of the present invention includes: a concentration step of concentrating an analyte in a sample in the vicinity of at least one of a pair of electrodes (1, 2) by applying a voltage to the pair of electrodes in the presence of the sample; and a detection step of generating plasma by applying a voltage to the pair of electrodes and detecting light emitted from the analyte excited by the plasma.
