high-field asymmetric waveform ion mobility spectrometry

acronym: FAIMS
synonym: RF-DC ion mobility spectrometry
https://doi.org/10.1351/goldbook.12425
Separation of ions at atmospheric pressure between two electrodes due to simultaneous application of a high potential asymmetric waveform, whereby ions migrate towards one of the two electrodes depending on the ratio of the high- to low-field mobility of the ion. A variable compensating DC potential is used to selectively transmit ions of interest.
