DIN EN 17298:2018-09

This European Standard specifies a method for the determination of benzoic acid and sorbic acid in animal feeding stuffs by high-performance liquid chromatography method with ultra-violet detection (HPLC-UV). The method is intended to be used for the determination of added benzoic acid and sorbic acid in feed additives, premixtures, compound feed and water. This method determines the total concentration of these organic acids and their salts.The working range of organic acids in the extract is between 5 mg/l and 100 mg/l.The method was successfully tested in an inter-laboratory study in concentrations between xx % up to xx %. The limit of quantification (LOQ) is: [to be completed]The lower limit of the working range depends on the matrix and the interferences encountered.
