Abstract
This lecture describes the spectrochemical characteristics of direct-current discharge plasmas generated by arc, spark, and glow discharges, which are generally employed as an excitation source for direct analysis of solid samples in atomic emission spectrometry. Emission spectra excited from arc discharge plasmas under ambient atmosphere are much different from those from low-pressure glow discharge plasmas. Excitation phenomena in glow discharge plasmas are described in detail so that a particular excitation mechanism occurring in the reduced pressure plasma, called charge transfer collision, can be well understood.
