Abstract
Spectrochemical analysis of fluorine by plasma emission spectrometry is described. First, plasma emission spectrometry and its present status are reviewed especially for the determination of nonmetallic elements. Secondly atomic emission spectrometry using helium microwave-induced plasma (MIP) at atmospheric pressure, which is an efficient excitation source for nonmetallic elements as well as metallic elements, is discussed as an element selective detector in gas chromatography (GC). Finally, the determination of fluorine in water samples by the GC/helium MIP system is shown as an experimental application of helium MIP to environmental and geochemical samples.
