A plasma source ion trap (PSIT) mass spectrometer has been modified to incorporate a radiofrequency octopole ion guide/collision cell between the ion source and the mass spectrometer. This modification allows ions sampled from the plasma to undergo reactions prior to mass spectrometric analysis. Thi
Perfluorokerosene can almost always be used as the mass calibrant for ions produced through electron impact ionization of compounds introduced into a mass spectrometer in the gas phase. Unfortunately, no completely universal calibrant is available for ions created by electrospray ionization (ESI) or
Inductively coupled plasma mass spectrometry (ICP-MS) for elemental analysis has been dominated since its introduction by instruments with quadrupole Γlters for mass separation. Although considerably impeded by isobaric ion interferences, ICP-MS with quadrupoles has nevertheless matured to become th
## Abstract The variations in the isotopic composition of calcium caused by fractionation in heterogeneous systems and by nuclear reactions can provide insight into numerous biological, geological, and cosmic processes, and therefore isotopic analysis finds a wide spectrum of applications in cosmoβ
