Quadrupole ion traps: What do they hold for glow discharge spectrometry?
- Oak Ridge National Lab., TN (United States)
This presentation will focus on the utility of quadrupole ion trap mass spectrometers for the analysis of glow discharge generated ions. The quadrupole ion trap is recognized among the organic mass spectrometry community as a highly sensitive mass analyzer. It is able to make efficient MS/MS and MS{sup n} analyses. As an ion storage device, selected reagent chemical ionization and other gas-phase ion molecule reactions can be effected. Such aspects of the quadrupole ion trap extend its utility beyond that offered by most mass analyzers. In the course of developing a glow discharge ion trap mass spectrometer for multielement analyses of solids, the authors have observed several phenomena fundamental to ion trap operation that hold promise for glow discharge (as well as inductively coupled plasma) mass analysis. The authors have found that low energy collisions with the helium bath gas can promote dissociation of many species commonly observed in both sector- and quadrupole-based GDMS. Energy, imparted to trapped ions by resonance excitation is useful in addressing interfered atomic ion signals. The analytical utility of such phenomena and factors affecting them will be presented.
