Abstract:
Ion mobility spectrometry (IMS) systems, devices, and associated methods of operation are disclosed herein. In one embodiment, an IMS system includes an ionization region configured to receive and ionize a sample into ionized molecules and a detector configured to detect ionized molecules. The IMS system also includes a drift region in between and directly coupled to both the ionization region and the detector. The drift tube includes a first ion gate proximate the ionization region and a second ion gate proximate the detector. The first and second ion gates are configured to alternately introduce a batch of ionized molecules toward the detector while the other is maintained open, thereby allowing accurate measurement of a drift time of the ionized molecules corresponding to a drift length that is a distance between the first and second ion gates.

Claim (Index 1):
A method for performing ion mobility spectrometry in a drift tube having a first ion gate and a second ion gate along a drift direction of the drift tube, the method comprising:\n ionizing a sample into ionized molecules; opening a first ion gate for a period to introduce a batch of the ionized molecules into the drift region having an applied electric field, thereby moving the ionized molecules along the drift direction toward the second ion gate while the ionized molecules are separated according to corresponding ion mobility values; maintaining the second ion gate open to allow the ionized molecules to reach a detector proximate the second ion gate, the detector detects the ionized molecules and records a first drift time of the detected ionized molecules; and subsequently,\n maintaining the first ion gate open to allow the drift region being filled with additional ionized molecules; \n opening the second ion gate for another period to introduce another batch of the additional ionized molecules to the detector, thereby allowing the detector to detect another batch of ionized molecules and records a second drift time; and \n deriving a final drift time corresponding to a drift length between the first and second ion gates based on both the first and second drift times.
