Hello, Achaladk 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, Achaladk, 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.

  • You can find answers to many student questions on our Q&A site, ask.wikiedu.org

If you have any questions, please don't hesitate to contact me on my talk page. Ian (Wiki Ed) (talk) 15:47, 26 January 2018 (UTC)Reply

Articles list

edit

The list of possible articles to edit is here: Wikipedia talk:Wiki Ed/Louisiana State University/Chemistry 4558 Mass Spectrometry (Spring 2018). Check for possible conflicts. mke sure that your list is on your talk page so that I can leave comments on your choices. --Kkmurray (talk) 18:00, 13 February 2018 (UTC)Reply

Article list

1.Laser ablation electrospray ionization
2.MALDI - Planning to add sample preparation techniques
3.Nanoelectrospray ionization - Electrospray ionization - Curently there's no separate page on nanoelectrospray. It has been described under electrospray.
4.DART ion source

Hi Achaladk,

1. Consider making the overview more easy to read. For instance, breaking the block of texts into three or four parts; where you start with a brief description of DART (maybe one or two short sentences). Then, continue with the results we typically get from DART ion source; and the different applications of those outputs. You could round it off briefly with how DART is being used. The inventors could be moved to the history section (if any).

See this overview on Mass Spec for instance: https://en.wikipedia.org/wiki/Mass_spectrometry.

2. Consider leaving spaces after periods and commas.

Thanks! Dideolu (talk) 18:32, 8 March 2018 (UTC)Reply

Article issues

edit

Your additions to the DART ion source article include passages nearly verbatim from a non-free source. This is an example of close paraphrasing, which is considered a infringement of copyright. Your edit was detected by automatic plagiarism detection software; you can see the report here, provided that you are logged into the Dashboard. For copyright reasons, the contribution had to be deleted. Please review the Plagiarism and Copyright training module before proceeding further. Thanks.

Edit summary content is visible in:

Please use the edit summary to explain your reasoning for the edit, or a summary of what the edit changes. You can give yourself a reminder to add an edit summary by setting Preferences → Editing →   Prompt me when entering a blank edit summary. Thanks! Kkmurray (talk) 16:28, 13 March 2018 (UTC)Reply

Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Direct analysis in real time, you added a link pointing to the disambiguation page Polar (check to confirm | fix with Dab solver). Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)
