GB 5009.268-2016 Translated English of Chinese Standard. GB5009.268-2016: National Food Safety Standard - Determination of multi-elements in foods
https://www.chinesestandard.net, 2. juni 2018 - 21 sider
This standard specifies inductively coupled plasma mass spectrometry (ICPMS) and inductively coupled plasma emission spectrometry (ICP-OES) for the determination of multi-element in foods. The 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, molybdenum, cadmium, tin, antimony, mercury, thallium, and lead in foods; the 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 in foods.
