本文介绍以TenaxGC吸附剂富集空气和肺泡气中的苯乙烯,经8702型热解吸器解吸后,直接由气相色谱分离检测。方法快速、灵敏、简便。方法的回收率95.1～98.5％,CV为2.0～4.9％。
This article describes the enrichment of air and alveolar gas with TenaxGC adsorbent styrene, the desorption of 8702-type thermal desorption, the direct detection by gas chromatography. The method is fast, sensitive and simple. The recoveries of the method ranged from 95.1% to 98.5% and the CVs ranged from 2.0% to 4.9%.
