Scope

The standard describes determination of the polyethylene glycol (PEG) content in aromatic and aliphatic non-ionic surfactants. It is applicable to all ethoxylated products soluble in methanol or methanol/water mixture. A portion of the sample solution is analysed by high performance liquid chromatography (HPLC) with evaporative light scattering detector (ELSD). The method is not applicable to PEG whose molecular weight is lower than 400.
