将微波等离子体炬原子发射光谱检测器(MPT-AED)用作气相色谱检测器,采用氩气作为工作气、载气和尾吹气,优化了气体流量参数;为了防止被测物质在管壁上的沉积,考察了氧气作为气相色谱-微波等离子体炬-原子发射光谱检测器(GC-MPT-AED)清洗气时对Cl,Br,I 3种元素发射信号的影响.为了考察检测器的分析性能,研究了GC-MPT-AED对有机化合物中Cl,Br,I 3种元素的检出限、线性范围、精密度及其响应特性,并将其结果与气相色谱-电感耦合等离子体-原子发射光谱检测器 (GC-ICP-AED)的结果作了比较,结果表明该仪器对Cl,Br的检测能力优于GC-ICP-AED的结果,线性范围与GC-ICP-AED结果相一致.
