For the determination of alkylbenezene sulfonate, Abbott's method has usually been used and it's result is always expresed as MBAS. By this method, however, quantitative analysis of ABS itself is not accurate, especially for its small amount.In this paper, we describe a new gas chromatographic analysis of ABS as methylsulfonate by sulfonylation followed by methylation. Flame photometric detector which has a selective sensitivity to sulfur was successfully used for detecting small amount of ABS without any influence of MBAS.Using this method, a linear calibration curve was obtained in the range of 20 to 1000ng and Abbott's method was found to be applied together. At the same time, it was found that ABS and LAS was able to distinguished and that charactaristic patterns of LAS leached from washed container were obtained in this method.
