Abstract

A method for selectively transmitting ions using a FAIMS device is disclosed. A first analyzer region is defined by a space between first and second spaced apart electrodes. A second analyser region is provided in operational communication with the first analyzer region. Ions are provided to the first analyzer region. The ions are coupled from the first analyser region to the second analyzer region. An asymmetric waveform is used to generate an electric field within the first analyser region and a compensation voltage is applied to prevent some ions from exiting the analyser region. Conditions are provided within the second analyzer region for effecting a second different separation of ions therein. Finally, the separated ions are trapped to accumulate ions within a trapping region thereof.
