An overview of commercial ICP mass spectrometers from different companies (quadrupole based ICP-MS with and without collision/reaction cell, double-focusing sector field instrumentation with single and multiple ion collectors, time-of-flight (ToF), ICP-ion trap-MS and non-commercial ICP-Fourier transform ion cyclotron resonance (FTICR) mass spectrometers is given in Figure 5.2. By using ion traps and FTICR mass spectrometers in ICP-MS isobaric interferences of atomic ions... [Pg.120]

Double-focusing Sector Field ICP Mass Spectrometers with Single Ion Collector (ICP-SFMS)... [Pg.131]

In double-focusing sector field ICP-MS spectrometers with single ion detection, the best abundance sensitivity with a mass difference of two is observed at medium mass resolution m/Am = 4400 (9 x 10 ). At low mass resolution mlAm = 400) an abnndance sensitivity for °Sr determination of 2 x 10 was measured in the author s laboratory. In quadrupole ICP-MS with and without a hexapole coUision cell, an abundance sensitivity of 6 x 10 and 6 x 10 , respectively, for determination in the presence of abundant with high ion intensity was determined by Boulyga et al. ° A significant improvement in abundance sensitivity for the determination of the isotope ratio has been obtained by multi-collector ICP-MS (Nu Plasma... [Pg.100]
