顶空气相色谱测定工业废气中乙醇含量,方法简单、快速。以蒸馏水吸收工业废气中乙醇,顶空进样经DB-624毛细管柱分离,氢火焰离子化检测器检测。实际操作证明,该法能满足工业废气和空气中的乙醇的监测。
Determination of ethanol in headspace gas by headspace gas chromatography is simple and rapid. The industrial waste gas was absorbed by distilled water, and the headspace sample was separated by DB-624 capillary column and detected by hydrogen flame ionization detector. Practice shows that this method can meet the industrial waste gas and air in the monitoring of ethanol.
