Abstract
A unique system incorporating features of inductively coupled plasma (ICP) and ion trap mass spectrometry (ITMS) is described. The combined ICP-ITMS system is characterized instrumentally and the initial performance features are presented. Bare atomic ions are observed for all elements, including previously problematic high oxygen bond strength elements that produced high levels of MOn + and M(OH)n + ions in early ICP-ITMS experiments. Approximate, unoptimized detection limits of 10–500 pg ml–1 are reported. Other advantages of the system include the complete destruction of typical ICP-MS polyatomic ions and the near complete neutralization of plasma Ar+, both of which contribute to much simpler spectra below 80 m/z.Keywords
