Characterization of a continuous source of single-charged transition-metal cluster ions is reported. Formation and cooling of the clusters occur via vaporization with an 8 kHz Cu vapor laser in a He flow. Cluster ions are mass-selected by a magnetic sector. Clustering and temporal behavior are exami
Designs of a quadrupole ion trap (QIT) as a source for timeβofβflight (TOF) mass spectrometry are evaluated for mass resolution, ion trapping, and laser activation of trapped ions. Comparisons are made with the standard hyperbolic electrode ion trap geometry for TOF mass analysis in both linear and
The use of an autoneutralizing fast neutral SF, beam (FNB) for secondary ion quadrupole mass spectrometry of refractive samples has been demonstrated previously. Here, we demonstrate the FNB technique for generation and high-resolution Fourier transform ion cyclotron resonance (FT-ICRl mass spectrom
