ICP-MS (Inductively Coupled Plasma Mass Spectrometry) or plasma source mass spectrometry represents the most sensitive and flexible method for the analysis of mass fractions of trace elements in geomaterials (rocks, minerals, water) and in chemical or technical products. The advantage of the method lies in the nearly complete ionization of many elements, which is achieved by using argon plasma at temperatures of up to 7000 °C and fast data acquisition. The Thermo Electron Element XR in the AB …
