The method is also suitable for any liquid-based sample if diluted in such a way that the diluted alkaline phosphatase activity has less than 7 000 milliunits per litre

ISO 3890-1 | IDF 75-1: 2009 - Milk and milk products - Determination of residues of organochlorine compounds (pesticides) - Part 1: General considerations and extraction methods Language:FR The method is suitable forThis standard describes general considerations and specifies extraction methods for the determination of residues of organochlorine pesticides in milk and milk products. A method for high fat products is specified in an annex. Guidance is given on the conduct of analyses in the presence of polychlorinated biphenyls (PCBs) in another annex. The methods are applicable to: alpha HCH; beta HCH; gamma HCH; aldrin dieldrin; heptachlor and heptachlorepoxide;
