Differential mobility spectrometry [DMS]; Field asymmetric-waveform ion mobility spectrometry [FAIMS]

Introduced: January 2021

Full Title

Full titles differ between systems:

IPC:

Investigating or analysing materials by the use of electric, electrochemical, or magnetic means > by investigating the ionisation of gases, e.g. aerosols; by investigating electric discharges, e.g. emission of cathode > Ion mobility spectrometry > Differential mobility spectrometry [DMS]; Field asymmetric-waveform ion mobility spectrometry [FAIMS]

CPC:

Investigating or analysing materials by the use of electric, electrochemical, or magnetic means (G01N3/00 – G01N25/00 take precedence; measurement or testing of electric or magnetic variables or of electric or magnetic properties of materials G01R) > by investigating the ionisation of gases, e.g. aerosols; by investigating electric discharges, e.g. emission of cathode > Ion mobility spectrometry > Differential mobility spectrometry [DMS]; Field asymmetric-waveform ion mobility spectrometry [FAIMS]
