Welcome

Hello, OviniW and welcome to Wikipedia! It appears you are participating in a class project. If you haven't done so already, we encourage you to go through our training for students. Go through our online training for students

If you need help, check out Wikipedia:Questions, ask me on my talk page, or ask your question on this page and then place {{Help me}} before the question. Please also read this helpful advice for students.

Before you create an article, make sure you understand what kind of articles are accepted here. Remember: Wikipedia is an encyclopedia, and while many topics are encyclopedic, some things are not.

Your instructor or professor may wish to set up a course page, and if your class doesn't already have one please tell your instructor about that. It is highly recommended that you place this text: {{Educational assignment}} on the talk page of any articles you are working on as part of your Wikipedia-related course assignment. This will let other editors know this article is a subject of an educational assignment and aid your communication with them.

We hope you like it here and encourage you to stay even after your assignment is finished!

Hello, OviniW, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing.

Peer Review

Below are my suggestions for your article. A. I found a few sources that appear to be primary, I think you should look through them and consider replacing them with secondary sources, if possible.

B. Below are some recommended changes:

1. In the introduction I would include that chemical ionization is a type of soft ionization and that electron ionization is hard ionization. You could then further explain how this accounts for the energy differences between the two ionization techniques.]]

2.In the mechanisms section I would also add that water can be used a reagent gas, I would explain when it can be used as well (In APCI). In addition, A mechanism showing water as the regent gas should be added as there is one for each of the other 3 gases.

3.In the Advantages and disadvantages section, I would include how Chemical ionization can be coupled to HPLC. In addition, the relatively lo cost can be included as an advantage.

4.Applications: An applications section should be added. The biochemical, biological, and medicinal applications should be discussed, as they are mentioned in the introduction, but not further information is given. Any other applications should also be included here.

5.Diagrams: I would add a lead diagram that demonstrates the general idea along with a diagram that demonstrates the decryption in the “principle of Operations section.” A diagram that shows APCI may also be useful.

6.Structure: The introduction should probably better define what chemical ionization is in the first sentence and then it can be stated that it is an area of mass spectrometry.
