DIN EN 14981:2006-12

This standard specifies a method for the identifying and quantifying of high boiling point solvents in finished liquid detergents and raw materials. The organic solvents are determined by gas chromatography. The sample is dissolved in ethanol and injected into a polar phase capillary column and the unknown solvent is identified by its retention time. After qualitative determination, the solvent is quantified using carvone (2-methyl-5-(1-methylethenyl)-2-cyclohexene-1-one) as internal standard.
