Scope

This Technical Specification describes a method for the quantitative determination of the total lead content in milk and milk products. The detection limit of the method, defined as three times the standard deviation of the blank determination, is 0,001 mg/kg for liquid products and 0,01 mg/kg for solid products if dry ashing is applied. For pressurized wet mineralization, these figures are the same for test portions containing 0,2 g of dry matter. Microwave mineralization allows for larger test portions, and detection limits are accordingly lower.
