本文提出了用国产GDX-103固体吸附剂采样管采集空气中硝化甘油的气相色谱方法。在给定的条件下,方法的检测限为1.0×10~(-4)μg/μl,解吸效率平均为100.8％,变异系数为6.16—6.40％,GDX-103对硝化甘油的穿透容量大于0.6mg。经现场测试,该法可用于工业卫生监测。
In this paper, a gas chromatography method using GC-MSG GDX-103 solid adsorbent sampling tube to collect nitroglycerin in air was proposed. Under the given conditions, the detection limit was 1.0 × 10 -4 μg / μl, the average desorption efficiency was 100.8% and the coefficient of variation was 6.16-6.40%. The penetrating capacity of GDX-103 to nitroglycerin was greater than 0.6mg. The field test, the method can be used for industrial hygiene monitoring.
