Multiple collector inductively coupled instrumentation

Figure 1 Outline of the multiple-collector inductively coupled plasma mass spectrometer (VG Elemental Plasma 54) at the University of Michigan (U-M). The U-M instrument is equipped with an extra 30-cm energy filter for high-abundance sensitivity measurements. (From Halliday et al., 1998b.)...

Given the importance of isotopic analysis to cosmochemical research, it is unsurprising that improvements in mass spectrometric methods and instrumentation have played a significant role in advancing the scientific field. The advent of multiple-collector (MC) inductively coupled plasma mass spectrometry (ICP-MS) in the early 1990s [10-13] is no exception in this regard. The success of this instrumental technique, which is now routinely used in well over 100 laboratories world-wide, has had an enormous effect on cosmochemistry, with many studies published over the last two decades that showcase novel methods and applications.
