Mass Spectrometry

Mass spectroscopy in Ion mobility

The analytical chemistry technique known as ion mobility spectrometry-mass spectrometry (IMS-MS) separates gas phase ions based on their interactions with a collision gas and their masses. Using an ion mobility spectrometer and a buffer gas, the ions are initially separated based on their mobility over millisecond duration. In a subsequent stage, the separated ions are put into a mass analyzer so that their mass-to-charge ratios may be calculated on a microsecond time period.
