Surface active agents - Technical alcane sulfonates - Determination of the mean relative molecular mass of the alcane monosulfonates and the alkane monosulfonate content

This standard establishes a unified method for determining the average relative molecular mass of alkyl monosulfonates and measuring their content within technical grade alkyl sulfonates. The scope focuses specifically on surfactants falling under the alkyl sulfonate category, providing a procedural framework to ensure consistent analytical results across the industry. The methodology outlines the necessary steps for sample preparation, instrument calibration, and the calculation of molecular mass averages based on experimental data. It also defines the specific tests required to quantify the concentration of alkyl monosulfonates present in the material. By adopting this unified procedure, manufacturers and laboratories can achieve comparable data regarding the purity and molecular characteristics of these chemical substances. The document serves as a technical reference for quality control processes involving these specific surfactant types, ensuring that measurements are conducted with a defined level of precision and repeatability. This approach facilitates international trade by aligning local testing practices with broader technical specifications for surfactant analysis.
