Abstract
The preparation and use of a simple charcoal tube is described for the collection of air samples for the determination of several commonly encountered halogenated and aromatic hydrocarbons of industrial hygiene significance. A rapid and efficient desorption procedure is employed. Specific parameters are presented for quantitative determination by gas chromatography. The method provides an easily applicable technique with the advantages of minimum field sampling equipment; and rapid, specific, accurate and economical determinations at atmospheric concentrations ranging from a few parts per million to several times the Threshold Limit Value.
