Abstract
This report describes a technique for concentrating traces of oxygenated organic compounds in air. The method depends upon the use of a 0.125 by 6-inch copper tube filled with an ordinary gas chromatographic column packing. When a sample of approximately 1000 ml of polluted air is pumped through the tube with a rubber aspirator bulb, a sufficient quantity of pollutants is absorbed for subsequent detection and identification by gas chromatography with a hydrogen flame detector. The limit of sensitivity is estimated to be about 5 ng/l. (Modified author abstract)
