车间空气中环氧丙烷可用活性炭管采样，丁醇解吸，FFAP色谱柱分离，氢焰离子化检测器检测。在给定条件下，方法检测限1．4×10(-3)μg／2μl，最小检出浓度0．35mg／m3（采气2L），穿透容量1．8mg／200mg活性炭；精密度、解吸效率、样品贮存稳定性等均符合要求．经测试验证，本法可用于工业卫生监测。
Workshop air propylene oxide can be activated carbon tube sampling, butanol desorption, FFAP column separation, hydrogen flame ionization detector detection. Under the given conditions, the detection limit of the method was 1.4 × 10 (-3) μg / 2μl with the minimum detectable concentration of 0.35mg / m3 (gas recovery of 2L) and the breakthrough capacity of 1.8mg / 200mg activated carbon; Desorption efficiency, sample storage stability, etc. meet the requirements. The test proved that this method can be used for industrial hygiene monitoring.
