Proposed bibliography and outline

edit

The objective of editing the page Chemical ionization (CI) is to increase its quality by addition of several important, but missing concepts on the topic.

1.History
2.Instrumentation for CI
Conditions needed for electron emission and CI
3.Ion generation by reagent gases
Reagent gases that can be used for CI
Chemical reactions for ion formation by isobutane and ammonia
4.Advantages of CI over other ionization techniques
5.Charge Exchange CI
Introduction
Chemical reactions
6.Improving the section Negative Chemical Ionization (NIC)
Two types of Reaction schemes and examples
7.Improving the section Atmospheric Pressure Chemical Ionization (APCI)

You need more secondary sources; try older reviews: doi:10.1021/ac60307a042, doi:10.1002/mas.1280050402, doi:10.1002/mas.1280020104.

Here is an image of a chemical ionization mass spectrometer that you might consider: File:NOAA_PAN_CIMS.jpg --Kkmurray (talk) 22:17, 13 March 2018 (UTC)Reply

Reevaluation of Article

edit

Based on the current criteria, I have given the article a C class rating. There are still a good number of primary sources, I recommend trying to replace these with secondary sources.
