Hello, I'm CAPTAIN RAJU. I wanted to let you know that one or more of your recent contributions to Liquid chromatography–mass spectrometry have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the help desk. CAPTAIN RAJU (T) 16:07, 4 November 2019 (UTC)
