Scope
Scope: This document specifies a rapid determination method for calcium in milk and dairy products. This document is applicable to milk and dairy products, such as raw milk, sterilized milk, processed milk, fermented milk, milk powder, and foods made primarily from dairy products for the rapid determination of calcium. Main technical content: The sample is mixed with polyethylene glycol to form a uniformly distributed solution under acidic conditions. Lanthanum solution is added as a release agent, and the sample is atomically absorbed and directly injected into an atomic absorption spectrometer for detection, with external standard quantification. Specifically, it includes the preparation of reagents and standards, instruments and equipment, analysis steps, result calculation and expression, etc.
