Breakthrough volumes of 90 organic vapors on Tenax GC adsorbent at 20 °C with a flow rate of 200 ml min-1 were measured to evaluate the capacity of Tenax GC adsorbent for the collection of trace organic compounds in ambient air at the ordinary temperature. The collection tube was a 5.5 mm i.d. × 21 cm long glass tube packed with 0.5 g of Tenax GC (60/80 mesh) supported by small plugs of quartz wool. The apparatus consisted of a Tedlar bag filled with a dilute vapor sample of the organic compound, the collection tube, a diaphram pump, a gas meter, and a flow meter. Breakthrough curve was obtained with gas chromatographic analysis using the periodic sample collected by a gastight syringe from the effluent cf the collection tube. Breakthrough volume is defined as the volume which the concentration of organic vapor in the effluent equals 10 % of the initial concentration. Test compounds were halogenated hydrocarbons, aliphatic amines, sulfur compounds, oxygen compounds, and hydrocarbons having from one to ten carbon atoms. The number of compounds that breakthrough volumes were more than 1 l, 10 l, and 100 l were 71, 47, and 4, respectively. These compounds were classified into eleven groups according to their structures, and in many groups, the logarithm of breakthrough volume showed good linear correlations with the boiling point, the reciprocal of the boiling point, the molecular weight, and the carbon number. These relations may be useful for estimating breakthrough volumes of another compounds having the similar structure.
