Liquid Electrode Plasma

Liquid electrode plasma atomic emission spectrometry (LEP-AES) is a method for elemental analysis based on the emission of plasma generated in a microchannel with a narrow central area. In recent years, it has been reported that the detection limit can be improved by collecting light from the axial direction, but the characteristics of axial light collection LEP-AES (A-LEP-AES) have not yet been studied much. In this study, the emission distribution and time dependence of Na in A-LEP-AES were observed and evaluated. As a result, strong emission was observed on the negative electrode side. It was also found that the emission of H and Na rose later than the emission of OH.
