Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. establishes an analytical method for low concentration benzene derivatives in ambient air, and studies desorption and analysis conditions The method adopts Tenax TA composite adsorption/secondary thermal desorption/capillary gas chromatography The relative standard deviation is between 4.35% and 10.91%, indicating good reproducibility The spiked recovery rate of benzene derivatives is greater than 95% The minimum detectable concentrations of benzene, toluene, xylene, and o-xylene are 0.08, 0.13, 0.25, and 0.27 μ g/m3, respectively. They are suitable for determining low concentrations of benzene derivatives in ambient air
