Scope

This standard specifies the method for determining the average relative molecular weight of industrial linear alkylbenzene sulfonate sodium. This standard applies to the determination of linear alkylbenzene. This standard does not apply to the determination of branched-chain alkylbenzenes (because the chromatographic peaks of branched-chain alkylbenzenes cannot be identified).
