以活性炭吸附环境空气中 1,2 -环氧丙烷 ,用二硫化碳洗脱 ,OV - 10 1:30m× 0 32mm× 0 2 5 μm毛细管柱低温分流进样分离 ,氢火焰离子化检测器测定 ,保留时间定性 ,峰高定量 ,采样吸附率达 99%。方法有较宽的线性范围 ,较高的灵敏度和精密度。当采样体积为 30L时 ,1,2 -环氧丙烷的检测限为 0 0 0
Epoxypropane in ambient air was first absorbed by active carbon, eluted by CS 2, separated by the type of capillary column of OV-101:30 m×0 32 mm×0 25 μm under low temperature. Then it was determined by hydrogen flame ionization detector, identified by retention time, quantified with peak height, the sampling adsorption efficiency was 99%. This method realized wide lineal limit, high sensitivity, precision. When the sample′s volume was 30 L, the detection limit was 0 005 mg/m 3.
