Animal feeding stuffs. Determination of selenium by hydride generation atomic absorption spectrometry (HGAAS) after microwave digestion (digestion with 65 % nitric acid and 30 % hydrogen peroxide)1 Scope This European Standard specifies a method for the determination of selenium in animal feeding stuffs by hydride generation atomic absorption spectrometry (HGAAS) after microwave pressure digestion. The method was successfully tested by an inter laboratory study of CEN TC 327 WG 4 in the range of 0,25 mg kg to 74 mg kg. The limit of quantification is 0,5 g l of the test solution which corresponds to the calibration standard 2. Using a test
