Abstract
Methods and systems for performing mass spectrometry are provided herein. In accordance with various aspects of the applicants' teachings, the methods and systems can utilize an ion mobility spectrometer operating at atmospheric or low-vacuum pressure to remove the major contributors to the contamination and degradation of critical downstream components of a mass spectrometer located within a high-vacuum system (e.g., ion optics, mass filters, detectors), with limited signal loss.
