Abstract
A multi-channel high field asymmetric waveform ion mobility spectrometer (FAIMS) is provided. The apparatus provides for substantially simultaneous FAIMS analysis of plurality of ions from a single sample. The apparatus has a analyzer region comprising a hollow electrode, a plurality of plate electrodes positioned parallel to and distanced from the hollow electrode, a contact for applying an high voltage asymmetric waveform to the hollow electrode and a plurality of contacts for applying a compensation voltage to the plurality of plate electrodes. A method for substantially simultaneous FAIMS analysis of plurality of ions from a single sample is also provided.
