In 1993,ICP (inductively coupled plasma) spectrometry and ICP/MS (mass spectrometry) were adopted by the Water Works Law and by the Basic Environmental Preotection Law for as offical methods for determining metals in water. The elements of water quality standards are aluminum, boron, cadmium, chromium, copper, iron, lead, manganese, molibdium, nickel, sodium and zinc. An ICP spectrometer has a mono-, polychrometer detection system and a sequential detection equipment, as well as characteristic functions such as simultaneous multi-elemental analysis. The linear dynamic ranges are four to six orders of magnitude for many elements and low detection limits for many elements. ICP/MS can also perform simultaneous multi-elemental analysis, and shows greater high sensitivity and less interference compared with an ICP spectrophotometer. The ICP and ICP/MS spectrometers, their principles, the function of the apparatus, interferences and applications to water and food analyses are described.
