气相色谱法测定室内空气中“三苯”的方法研究

Determination of benzene, toluene and xylene in indoor air by GC

针对室内空气中“三苯”特点,在居住区大气中“三苯”的测定方法——气相色谱法(GB 1737-89)的基础上,进一步优化该方法的采样时间、采样流量等条件,使优化后的测定方法更加适应室内空气监测需要的准确性、简便性、快速性的特点。

Aiming at the characteristics of benzene, toluene and xylene in indoor air, this paper is optimizing the samplifing time and sampling flux on the base of the method of GB11737 -89 to make it more fit the need of accuracy, simple and speediness in monitoring indoor air.
