DIN EN 17212:2018-01

This European norm defines a high-performance liquid chromatographic method (HPLC) for the analysis of melamine and cyanuric acid in the concentration range between 1 mg/kg and 100 mg/kg in feed by mass spectrometric detection (MS). The method is suitable for both screening and confirmation (quantification) purposes. The limit of quantification of the method has been demonstrated to be better than 0,3 mg/kg for melamine and 0,6 mg/kg for cyanuric acid. The quantification of concentrations above 100 mg/kg is possible but the method has to be validated by the operator.
