标准范围
ISO 14674IDF 190:2005规定了一种用于测定牛奶和奶粉中黄曲霉毒素M1(AFM1)含量的方法，该方法包括使用免疫亲和层析然后使用薄层层析(IAC-TLC)的净化步骤。该方法适用于原料奶、低脂或脱脂液态奶和奶粉。通常可以测定的AFM1的最低量为2ng，其对应于液态奶或溶解奶粉接近0.10微克/升的定量限（对于20微升的斑点）。
ISO 14674|IDF 190:2005 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 micrograms per litre for liquid milk or dissolved milk powder (for a spot of 20 microlitres).
