摘要： 氧屏蔽氩微波等离子体炬(OS-Ar-MPT)是对Ar-MPT新光源的一个重大改进.本文主要探讨了屏蔽气氧气流量变化时对该新光源背景发射光谱及某些元素的原子线、离子线发射的影响.结果表明,该光源简单的背景发射十分有利于作原子发射光谱分析,同时它对多数元素的原子发射线信背比都有明显的改善,是一种很有发展前途的新光源.

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
