ABSTRACT:
A combined rf-only/FAIMS apparatus is disclosed for use in mass spectrometry and other applications. The disclosed apparatus includes a plurality of curved electrodes arranged around a central ion transmission channel. FAIMS functionality is removed electronically when not desired by application of radio frequency (rf) waveforms to the curved electrodes.
