ABSTRACT:
A combined rf-only/FAIMS analyzer is disclosed for use in mass spectrometry and other applications. The disclosed apparatus includes a plurality of flat-plate electrodes arranged around a longitudinal axis of the apparatus so as to define generally a parallelogram in a cross section taken in a plane that is normal to the longitudinal axis. FAIMS is removed electronically when not desired by application of radio frequency (rf) waveforms to the flat-plate electrodes.
