Animal feeding stuffs. Determination of inorganic arsenic by hydride generation atomic absorption spectrometry (HG-AAS) after microwave extraction and separation by solid phase extraction (SPE) Ingestion-build-68772 Note: Syntax in BS IEC1 Scope This European Standard describes a procedure for the determination of inorganic arsenic in animal feeding stuffs of marine origin by Solid Phase Extraction (SPE) and Hydride Generation Atomic Absorption Spectrometry (HG AAS). The method has been successfully tested in a collaborative trial with a working range from 0,19 mg kg to 2,7 mg kg (HORRATvalues < 2; HORRAT value is Horwitz Ratio value). The LOQ of the method is usually approximately
