Abstract
An ion mobility spectrometry method comprising (i) applying a voltage difference between a first electrode of an ion gate and a second electrode of the ion gate to prevent ions from leaving a reaction region of an ion mobility spectrometer; (ii) opening the ion gate to allow the ions to travel from the reaction region into a modification region between the first electrode and the second electrode; (iii) applying a radio frequency, RF, voltage between the first electrode and the second electrode to fragment the ions in the modification region to provide daughter ions; (iv) allowing the daughter ions to travel from the modification region into a drift region of the ion mobility spectrometer towards a collector; (v) closing the ion gate; and (vi) determining the time of flight of the daughter ions from the ion gate to the collector.
