毛细管气相色谱法测定室内空气中挥发性苯系物

Determining Benzenes in Indoor Air with Capillary Column Gas Chromatography

用毛细管气相色谱法可快速测定室内空气中苯系物.通过测定,结果表明:活性炭富集采样、CS2萃取、毛细柱分离、FID检测,方法精密度、准确度良好,检出限在0.02mg/m3～0.05mg/m3,适用于室内环境空气中苯系物的实用性测定.

Objective to rapidly determination of the Benzenes of indoor air, a method is established with capillary column gas chromatography in this paper. The results showed that： activated carbon enrichment collection, CS2extraction, capillary column separation, flame ionization detector are proved to be accurate, sensitive and reliable. The limit of detection was 0.02 mg/m^3-0.05 mg/m^3. It issuitable for the practical test analysis of the Benzenes of indoor air.
