Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. determined the minimum quantitative concentrations of benzene derivatives in indoor air by adsorbing them on activated carbon, desorbing them with carbon disulfide, and using gas chromatography and hydrogen flame ionization detector. The results showed that benzene had a concentration of 0.015 mg/m3, toluene had a concentration of 0.076 mg/m3, and xylene had a concentration of 0.11 mg/m3; The relative standard deviation is: within day: 2.51%~2.93%; Daytime: 3.35%~4.25%; The recovery rate ranges from 95.4% to 101.3%. This indicates that the method has good precision and high accuracy, is simple, and easy to promote and apply.
