Abstract
A High-Pressure Ion Trap operating at pressure ~1 Torr is a core component of the portable hand-held mass-spectrometric gas analyzer. A comprehensive mathematical model of the HPIT is described in this paper. The influence of the instrumental parameters (gas composition, pressure, and temperature; applied voltages; ion trap size and geometry) and ion properties (mass, diffusion, and mobility) on the ion trap analytical parameters (mass-spectral peak position, height, and width) is examined. The model explained the difference between a high-pressure and regular low-pressure ion trap.
