摘　　要：报道了一种气相色谱用微波等离子体炬原子发射光谱检测器（ＧＣ－ＭＰＴ－ＡＥＤ），以氩气为载气和等离子体工作气体，氧气为清洗气和屏蔽气，研究了ＭＰＴ－ＡＥＤ对有机化合物中碳元素的响应特性，探讨了氧气作为ＧＣ－ＭＰＴ－ＡＥＤ屏蔽气对碳元素检测性能的影响．The present paper deals with a microwave plasma torch atomic emission detector for gas chromatography, argon was used as the carrier and support gas, oxygen as scavenger and sheath gas, respectively. The response characteristics of the MPT AED for carbon in organic compounds was studied. The effect of oxygen sheathing on the detection performance for carbon was discussed.
