Spectrometric and high-performance liquid chromatographic methods.

This Section of BS 3762 describes two methods for the determination of the toluenesulphonates or xylenesulphonates content of formulated detergents.

In method A, the alkylbenzenesulphonates content is determined spectrometrically as sodium toluenesulphonate or as sodium xylenesulphonate, using calibration graphs prepared with appropriate reference materials.

Method B, which is based on a reversed-phase high-performance liquid chromatographic (HPLC) separation technique, separates and quantifies mixtures.

Method A is for use if no HPLC equipment is available, or if mixtures of toluenesulphonates and xylenesulphonates are not suspected. Method A is not applicable to samples containing compounds that absorb radiation at 220 nm and that are not extracted by diethyl ether, e.g. alkylphenolethoxylates. Method B may be used with samples that contain single or mixed compounds.
