Notes[edit]

Couple of points:

1. Current article importance rating is low - FAIMS is becoming an increasingly important technique. The development of new commercial pre-mass spec stages by Owlstone Inc. and Thermo is resulting in increasing uptake by academics and industry. I would recommend therefore that the importance is raised.

2. The article currently states that FAIMS 'is a mass spectrometry technique in which ions at atmospheric pressure...'. FAIMS is not a 'mass spectrometry technique'. The separation possible by FAIMS is based on differences in the ion shape/charge ratio rather than the mass/charge ratio that MS relies on. Also mass spectrometry requires a vacuum, whereas FAIMS separation is absolutely reliant on the presence of other spectator molecules with which analyte ion collide. It is incorrect however to say that FAIMS takes place at 'atmospheric pressure', as it is possible to modulate the achievable ion separation by adjusting the pressure (and therefore the number of collisions an ion experiences) positively or negatively.

I will address these issues as I edit the page.

Moving the page[edit]

I would like to move this wiki page to High-field asymmetric-waveform ion mobility spectrometry, essentially removing the hyphen between ion and mobility in the title. Any objections or feedback, please leave a comment. Gab Brasseur (talk) 22:28, 20 October 2021 (UTC)[reply]
