GB 5009.268-2025 National Food Safety Standard: Determination of Multiple Elements in Food

Scope

The first part of this standard specifies the methods of inductively coupled plasma mass spectrometry and inductively coupled plasma emission spectrometry for the determination of multiple elements in food, and the second part specifies the method of inductively coupled plasma emission spectrometry for the determination of multiple elements in compounded food nutritional fortifiers.
The first method in the first part 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 food. The second method in the first part 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, and zinc in food.
The second part is applicable to the determination of calcium, copper, iron, potassium, magnesium, manganese, sodium, phosphorus, and zinc in compounded food nutritional fortifiers that are made from mineral raw materials, with or without the addition of additives.
