Abstract
The invention provides, in various embodiments, systems and methods relating to enhancing the filtering and detection capability of ion mobility based systems by various techniques to counteract a charge buildup in the ion mobility based system.
Claims30
A system for analyzing ions of a sample comprising:
- a flow path for flowing ions of a sample,
- an ion filter for generating an asymmetric field and a compensation field in said flow path to pass through selected ions in the flow path, and
- a controller for counteracting a charge buildup within the flow path.
A method for analyzing ions of a sample comprising:
- flowing ions of a sample within a flow path,
- filtering ions within the flow path by applying an asymmetric field and compensation field, and
- counteracting a charge buildup within the flow path.
