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.

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.
