1 Scope This standard specifies the inductively coupled plasma-mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) for the determination of multi-elements in foods. Method I is applicable to the determination of boron, sodium, magnesium, aluminum, potassium, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, strontium, molybdenum, cadmium, tin, stibium, barium, mercury, thallium and lead contents in foods; Method II is applicable to the determination of aluminum, boron, barium, calcium, copper, iron, potassium, magnesium, manganese, sodium, nickel, phosphorus, strontium, titanium, vanadium and zinc contents in foods. Method I Inductively Coupled Plasma-mass Spectrometry (ICP-MS) 2 Theory Use inductively coupled plasma-mass spectrometer to determine the content in the sample after digestion, conduct the quantitative analysis with specific mass number (mass-to-charge ratio, m/z) and conduct quantitative analysis in external standard method with that the strength ratio of mass spectrum signals of to-be-determined elements and internal standard element in direct proportion to the concentration of to-be-determined elements. 3 Reagents and Materials
