What kind of lasers are used in mass spectroscopy? 10:58, 11 September 2021 (UTC)

SFAIK, none. Electron beams can be used, but not sure laser-ablation is a big thing in this subfeld. So I just edited that detail out and added what a plain (i.e. light) spectrometer is. (More likely, this being a laser-lab perhaps making use of novel materials, not a primarily materials-analysis one) is.)
Any actual Laser Lab-Persons reading this might know otherwise, of course, if they can stop melting things for fun and bother to explain things to us... 18:09, 11 September 2021 (UTC) I don't know any other uses for lasers in mass spectroscopy, but MALDI (Matrix-Assisted Laser Desorption Ionization) is commonly used in biochemistry and polymer chemistry (and chemistry of any other fragile macromolecule) to ionize molecules in the sample without breaking (fragmenting) them. It is called a "soft" ionization method due to it's propensity to leave the ions in one piece - something shared with ElectroSpray Ionization (ESI), which is commonly used for same purposes, but doesn't use lasers. 20:15, 11 September 2021 (UTC)
So, yeah, your link says that lasers are used for ionization (I think of large molecules?) prior to mass spectrometry. The information removal would have been in error. 20:59, 11 September 2021 (UTC)

...popover on the page. Didn't seem to stop me editing/previewing. Is it in response from all the (other) Cloudflare errors we've been getting recently, someone activiting a safety-net? 18:09, 11 September 2021 (UTC)
