Multiple collector inductively coupled plasma mass spectrometry

Multiple-collector inductively coupled plasma mass spectrometry (MC-ICPMS) combines sector-field ICPMS with a multiple collector detector system and has recently emerged as an alternative to TIMS for precise U-Th isotope measurement. The full potential of MC-ICPMS has yet to be realized. Yet despite this, its performance in high precision isotope measurement already challenges and, in some cases, surpasses that ever achieved by TIMS (e.g., Lee and Halliday 1995 Blichert-Toft and Albarede 1997).

Several isotopes (see Isotopes Isotope Labeling) of Cd are known, and 8 are stable (Table 3). For " Cd and " Cd, the nnclear spin is 1/2 and they are used for NMR studies of Cd compounds and in biological fields (see Cadmium Organometallic Chemistry). " Cd is used in the nuclear industry because of its high neutron cross section. Unstable isotopes are prepared from nuclear reactions. Cd stable isotope composition in geological and meteorite samples has been investigated using multiple collector inductively coupled plasma mass spectrometry. ...
