Resumo

An indicating oxidant scrubber has been developed for the chemisorptive or cryogenic collection of dimethylsulphide and potentially other reduced atmospheric trace gases, for subsequent gas chromatographic analyses. The scrubber, based on potassium iodide, was not exhausted after exposure to approximately 200 l of ambient air and compared favourably with scrubbers used in other studies. When used in series, two of these filters will provide a visual indication of the oxidant breakthrough volume.
