Title:
DEVICE FOR SEPARATING, ENRICHING AND DETECTING IONS
Document Type and Number:
WIPO Patent Application WO/2010/060380
Kind Code:
A1
Abstract:
A device for separating, enriching and detecting ions comprises: a gas passage, in which a carrier gas flows at a uniform rate; an ion source; multiple electrodes provided in the gas passage, which are applied with electric voltage respectively, thus at least a electric field is produced along the axis of the gas passage; an ion detector; and an ion outlet, by which specific enriched ions will be guided across the side wall of the gas passage toward the ion detector and be analyzed. The device could enrich ions utilizing the following characteristic: compound ions with specific ion mobility could maintain a dynamic balance for a period of time in a flow field under the combination of a carrier gas and a suitable electrical field against the direction of the carrier gas. Simultaneously, multiple compound particles with different ion motilities could be separated and enriched at positions with different electrical field intensities in a flow field in the same manner. The device also comprises synchronously export latitudinally enriched ions at different positions in a flow field, and performs later mass analysis using a mass spectrometer.
