Scope

The Part I of this Standard specifies the inductively coupled plasma mass spectrometry and
inductively coupled plasma emission spectrometry methods for the determination of multiple
elements in foods; and the Part II specifies the inductively coupled plasma emission
spectrometry method for the determination of multiple elements in nutritional fortifiers of
compound foods.
The Method I of the Part I is applicable to the determination of lithium, boron, sodium,
magnesium, aluminum, phosphorus, sulfur, potassium, calcium, titanium, vanadium, chromium,
manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, rubidium, strontium,
molybdenum, cadmium, tin, antimony, barium, mercury, thallium and lead in foods; and the
Method II of the Part I is applicable to the determination of aluminum, arsenic, boron, barium,
calcium, cadmium, cobalt, chromium, copper, iron, potassium, magnesium, manganese,
molybdenum, sodium, nickel, phosphorus, lead, sulfur, selenium, tin, strontium, titanium,
vanadium and zinc in foods.
The Part II is applicable to the determination of calcium, copper, iron, potassium, magnesium,
manganese, sodium, phosphorus and zinc in nutritional fortifiers of compound foods with
minerals as raw materials, with or without auxiliary materials.
Part I Determination of Multi-Elements in Foods
Method I Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
