The Application and Research Progress of Inductively Coupled Plasma Mass Spectrometry in Environmental Monitoring Area

Inductively Coupled Plasma Mass Spectrometry is one of the fastest growing technique for measuring concentrations of trace element. ICP-MS provides many advantages, including very low detection limits, wide dynamic range, good control of interferences, high precision, multi-element, fast analysis, etc. ICP-MS can be combined with other separation technology and sample pretreatment methods. Because of its inherent advantages, ICP-MS has made great progress. In this paper, the basic principle and structure of ICP-MS were introduced. The comparisons of ICP-MS and other analytic techniques were introduced. The development trend of ICP-MS was introduced. The application and research progress of ICP-MS in environmental monitoring area and environmental science were introduced in detail.
