Development of a portable ion trap mass spectrometer
Abstract
Mass spectrometry is a valuable research tool that is capable of providing both qualitative and quantitative information simultaneously. Previously, mass spectrometers have been relegated to the laboratory or have been taken to the field with only limited capability. A miniature cylindrical ion trap mass spectrometer has been developed to provide both the functionality and the small size that is required for field use. A description of the hardware, software and preliminary data are included. A novel detection scheme in use in quadrupole ion trap mass spectrometers was developed in an attempt to provide ion detection with reduced power requirements and the capability to re-measure the same ion population. Broadband image current detection on the entire end-cap electrode, rather than on a small pin electrode, as was previously done, is described.
