Preliminary Studies on the Background Emission and Emission Properties of Some Elements from OS-Ar-MPT

Abstract

Abstract: OS-Ar-MPT is an excellent improvement to the Ar-MPT excitation source. The effect of O₂flow rate on the background emission and some atomic and ionic lines in the new source is exploited in this paper. The results show that the simplicity of the background emission of the OS-Ar-MPT is beneficial to the atomic emission spectrometry. Moreover, signal to background ratios of most emission lines of all elements studied have been significantly improved. The prospect of the new source is promising.

Key words: Oxygen-sheathing, MPT, Excitation source, Background emission
