Fundamental Principles and Performance for a Low Vacuum Mass Spectrometer

This research is intended to further enhance the robustness and reduce the size and cost of portable mass spectrometer by getting rid of turbo pump without sacrificing much of performance. A low vacuum mass spectrometer (LVMS) was developed to be operated at a pressure of ~ 10 Pa without using turbo pump. FWHM ≤ 1 Th can be achieved for mass range of 18 – 400 Th. Such miniature prototype was developed for VOCs detection with membrane inlet or coupling with microGC for enhanced qualitative gas analysis.
