Inductively Coupled Plasma Mass Spectrometer (ICP-MS)








Model: ICP-MS 2000
Inductively coupled plasma mass spectrometry (ICP-MS), popularized since 1980's, is a new technique for micro-(10-6), trace-(10-9), and ultra-trace-scale (10-12) element analysis with a variety of advantages, such as applicable to analyze the majority in the periodic table of elements, low detection limit, wide linear (dynamic) range, low interference, high accuracy, high speed and isotopical analysis.
