摘要
作者研究以Ｃａｒｂｏｔｒａｐ作吸附剂，采集大气中卤烃化合物，并直接采用热脱附气相色谱法，对新型吸附剂Ｃａｒｂｏｔｒａｐ的突破体积、回收率、分析精度、固定液的选择等作了试验。本法具有灵敏度高、色谱峰形好、吸附剂可反复使用等优点。
s:The carbotrap adsorbent has been studied;the air halocarbon compounds are collected and analysed by thermal desorption gas chromatography.The analytical precision of sampling and desorption,percent recoveries,breakthrough volumes of new adsorbent carbortap are investigated.The features of this method are high sensitivity,fine chromatographic peak,repeatable uses of adsorbent.Air halocarbon compounds of ppb level can be determinated.
