Numerous changes made to grammar, language usage and punctuation in the article. The information is very solid but sometimes passages were simplified for clarity. Kmcke14 (talk)

FT- ICR EI - MS section reads like a journal review. Is this a necessary paragraph? Kmcke14 (talk) 22:12, 17 April 2016

Diagram

reqdiagram| electron ionization, for example [1], indicating vertical ionization and reaction coordinate to help explain fragmentation --Kkmurray (talk) 03:56, 29 July 2008 (UTC)

Tried to match up with your example. Hope this is what you had in mind.Edguy99 (talk) 19:17, 30 April 2009 (UTC)

I was thinking more of the Morse potential-like curves to illustrate vertical ionization (Franck–Condon principle). --Kkmurray (talk) 19:58, 30 April 2009 (UTC)

I added a diagram graphically illustrating the interaction; not the Energy states. Removed reqdiagram.

Charge balance

• • • RE: First diagram in main page

This is not relevant to the above discussion, but shouldn't the first diagram in the main page show either "2+" for the resultant ion, or "+ e-" to show that only a single electron was lost? Only a detail, but in its current form the diagram might confuse someone new to the basics. Otherwise a great diagram by the way. Thanks. — Preceding unsigned comment added by 138.253.77.147 (talk) 16:44, 17 September 2016 (UTC)

Both diagrams appear to be correct and show the correct charge balance:${\ce {{M}+e^{-}->{M^{+\bullet }}+2e^{-}}}$. The left side is net -1 charge from the electron and the right side is net -1 from the positive ion and two electrons. It might be better if the + indicating the charge and the + for the reaction were different fonts, though --Kkmurray (talk) 18:08, 17 September 2016 (UTC)

Forensics Discussion

Why was the forensics application section only limited to detection of medicinal drugs, and highly specific ones at that? Why not discuss current advances and regular applications of EI in the forensics field? Lauren mun (talk) 02:55, 28 January 2018 (UTC)

Ionisation is a process

Ionisation by electron impact is a physical process yet this article barely describes that process at all. The bulk of this article describes a single, particular application of electron ionisation, namely in mass spectroscopy. Where is the description of the general physical process of electron interaction with atoms or molecules? This article should either be renamed as 'mass spectroscopy ion source' or something similar or completely rewritten. 212.159.76.165 (talk) 10:07, 22 August 2018 (UTC)
