Figure 5.2 Overview of ICP-MS instrumentation quadrupole-based ICP-MS with and without colli-sion/reaction cell, sector field ICP-MS with single ion collector (ICP-SFMS) and multiple ion collector ICP-MS (MC-ICP-MS) and time-of-flight ICP-MS.

As an alternative to commercial quadrupole based ICP-MS measurements at low mass resolution ( / 300), in 1996 Yiang and Douglas15 proposed a quadrupole ICP-MS system which allows a maximum mass resolution of 9000. At a mass resolution of 5000 the sensitivity was comparable to that of a commercial double-focusing sector field ICP-MS operated at the same mass resolution. Due to the very high continuum instrumental background of about lOOOcps no commercial high resolution quadrupole instrumentation with an inductively coupled plasma source exists and the development of high resolution quadrupole based ICP-MS has ceased.

Figure 6.5a illustrates part of a real mass spectrum of a radioactive waste solution in the mass range 180-250 u measured by double-focusing sector field ICP-MS (ELEMENT, Thermo Fisher Scientific) at low mass resolution. In this mass spectrum, atomic ions of Re at mass 185 u and 187 u with isotope abundances of 37.4 % and 62.6 %, respectively (Re was used for "Tc precipitation),...
