ISO 14674 | IDF 190: 2005: Milk and milk powder - Determin. of aflatoxin M1 content - Clean-up by immunoaffinity chromatography and determination by thin-layer chromatography Language:EN This routine procedure is appliedThis standard specifies a method for the determination of the aflatoxin M1 (AFM1) content of milk and milk powder by a method including a clean up step using immunoaffinity chromatography followed by a thin layer chromatography (IAC TLC). The method is applicable to raw milk, low fat or skimmed liquid milk and milk powder. The lowest quantity of AFM1 that can commonly be determined is 2 ng, which corresponds to a limit of quantification close to 0,10
