Hello, I'm Oshwah. I wanted to let you know that I removed one or more external links you added to Matrix-assisted laser desorption/ionization because they seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page or take a look at our guidelines about links. Thanks.  ~Oshwah~  (talk) (contribs)   15:25, 27 March 2018 (UTC)
