Conditions for thermal desorption of trace amounts of toxic volatile organic compounds in the atmosphere collected on Tenax GC, a polymer of 2,6-diphenyl-p-phenylene oxide, were investigated for gas chromatographic analysis. Optimum conditions for the Tenax GC adsorbent was found to be 250℃ by a high heating rate. Under these conditions, 78 toxic compounds recovered were measured and basic data were obtained. Fifty-five of these compounds were found to have recovery above 90%, 17 compounds 80-90% and three compounds 70-80%. Therefore, 75 volatile organic compounds at sub-ppb levels in the atmosphere can be determined by gas chromatography with Tenax GC after adsorption at ambient temperature followed by thermal desorption at 250℃. The relative standard deviations were less than 15%.
