Systems and Methods for Ion Separation

摘要

A system for analyzing a sample includes a source configured to generate ions from constituent components of the sample; a mobility separation device, a plurality of ion channels, and a mass analyzer configured to determine the mass-to-charge ratio of the ions. The mobility device is configured to separate ions received from the source based on the mobility in a gas. The mobility separation device provides a gas flow in a first direction and an electric field gradient along a second direction such that ions move in the first direction and drift according to their mobility in the second direction and are sorted based on their respective mobility. The ion channels are arranged adjacent to the mobility separation device such that ions from the mobility separation device are directed to different channels according to their respective mobility.
