Analytical techniques have been developed for the collection and determination of gas phase dimethyl sulfate and monomethyl sulfuric acid based on collection of the alkyl sulfate compounds with both denuder tubes and resin sorption beds and analysis of the collected material by ion chromatography. Gas phase dimethyl sulfate and monomethyl sulfuric acid have been identified in Los Angeles using these techniques. The data indicate that dimethyl sulfate is present in both particles and in the gas phase. The concentration of gas phase methyl sulfates was found to be several micrograms/cu m. These species thus account for a significant fraction of the total sulfur budget in the Los Angeles Basin during the sample period. (Copyright (c) 1986 American Chemical Society.)
