METHOD AND SYSTEM FOR VACUUM DRIVEN DIFFERENTIAL MOBILITY SPECTROMETER/MASS SPECTROMETER INTERFACE WITH ADJUSTABLE RESOLUTION AND SELECTIVITY |
摘要 |
<p>A mass spectrometer system including a differential mobility spectrometer and a mass spectrometer at least partially sealed to, and in fluid communication, with, the differential mobility spectrometer, together with a related method, are provided. The mass spectrometer system can be operable to, and method can comprise, a) maintaining the differential mobility spectrometer at an internal operating pressure; b) providing ions to the differential mobility spectrometer; c) maintaining the mass spectrometer at a vacuum pressure lower than the internal operating pressure to draw a gas flow including the ions through the differential mobility spectrometer and into the vacuum chamber; and, d) modifying the gas flow between the differential mobility spectrometer and the mass spectrometer to change a gas flow rate through the differential mobility spectrometer.</p> |
