Analytical methodology has been developed for the measurement of linear alkylbenzene sulfonate (LAS) in a broad spectrum of water and wastewater samples. In addition to providing the homolog‐isomer composition of LAS, the gas chromatographic procedure has been quantified by incorporation of an internal standard to provide a specific measurement of LAS. The applicability and sensitivity of the standard, but non‐specific, methylene blue active substances (MBAS) method have been increased by concentration and clean‐up steps that eliminate many of the known interferences. The gas chromatographic procedure has provided specific, as well as significant, information relative to the removal of LAS in the waste treatment process.
