The lowest level of validation is 0,08 µg/kg for whole milk powder, i.e. 0,008 µg/l for reconstituted liquid milk. The limit of detection (LOD) is 0,05 μg/kg for milk powder and 0,005 μg/kg for liquid milk. The limit of quantification (LOQ) is 0,1 μg/kg for milk powder and 0,01 μg/kg for liquid milk. The method is also applicable to low-fat milk, skimmed milk, low-fat milk powder and skimmed milk powder.
