| 摘 要： | 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,I3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,I3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-IC

| Abstract: | The present paper deals with a microwave plasma torch atomic emission detector for gas chromatography Argon is used as support gas, carrier gas and make up gas. The effect of oxygen scavenger gas on the detection performance for chlorine, bromine and iodine is discussed. Detection limits, dynamic ranges, relative standard deviations and response characteristics of GC MPT AED for chlorine, bromine and iodine in organic compounds were studied. The results are favorable in comparing with GC ICP AED. |
