气相色谱用氩微波等离子体炬发射光谱检测器——对Sn,P,Si和B金属有机化合物响应特性的研究

报道了一种气相色谱用氩微波等离子体炬原子发射光谱检测器(GC-MPT-AED),以氩气为载气、等离子体工作气和尾吹气,探讨了不同气体作等离子体清洗气和屏蔽气时对Sn,P,Si,B等元素响应特性的影响.研究了系统对Sn,P,Si,B等元素的检出限、线性范围和精密度,并对乐果乳油中磷元素的含量进行了测定.

Gas Chromatography with Microwave Plasma Torch Atomic Emission Spectrometry Detector for the Determination of Sn, P, Si and B

The present paper deals with an argon microwave plasma torch atomic emission spectrometry detector(GC MPT AED) for gas chromatography, argon was used as the carrier gas, plasma support gas and make up gas. The effect of different kind of gases as the plasma scavenger gas, sheathing gas on the response characteristics for Sn, P, Si and B is discussed. Detection limits, dynamic range and relative standard deviation of the elements Sn, P, Si and B was studied, and the content of element P in Rogor emulsifying oil was also determined.
