Analytical techniques have been developed for the collection and determination of gas-phase dimethyl sulfate and monomethyl hydrogen sulfate. The techniques include the collection of the gas-phase species in diffusion denuders that are selective for monomethyl hydrogen sulfate or that collect both dimethyl sulfate and monomethyl hydrogen sulfate. Dimethyl sulfate and monomethyl hydrogen sulfate are also collected in filter pack adsorbent bed combinations which allow for the separate determination of both dimethyl sulfate and monomethyl hydrogen sulfate or for their joint collection and determination. The sampling and analysis techniques thus allow for the determination of both di- and monomethyl sulfates each by two independent procedures with a detection limit of 2-10 nmol by ion chromatography. Data obtained with the adsorbent bed sampling techniques indicate that gas-phase dimethyl sulfate is present at very low concentrations in the flue line of a coal-fired steam plant.
