      <subfield code="a">In the activated charcoal/gas chromatographic method for the determination of trace organic volatiles in the atmosphere, carbon disulphide is widely used as the desorbing solvent. When working a high sensitivities, trace impurities in most batches of the solvent may give signals which appear in the chromatogram in the regions of interest</subfield>
