Abstract
Gas chromatography determination of benzene, toluene and xylene in indoor air by active carbon adsorption-CS_2 (solvent)parse method was studied. According to the national standard of GB11737-89, some conditions were improved, and the accuracy, precision and stability of this method were studied. The results show that this improved method is suitable for determination of benzene, toluene and xylene in indoor air.
