Abstract
Liquid electrode glow discharge has been developed and widely used in analytical chemistry due to its advantages such as small-size, low power-consumption, easy operation, high electron density and simple experimental setup. This review focused on the recent progress on the application of various liquid electrode glow discharge microplasma in atomic spectrometry over the past five years, including liquid cathode glow discharge, liquid anode glow discharge, and alternating current driven liquid electrode glow discharge. Particularly, their applications as excitation sources for optical emission spectrometer and chemical vapor generation, as well as their hyphenation with other techniques of chemical vapor generation were emphatically described. The development trend of liquid electrode glow discharge was also prospected.
