Common contaminants in mass spectrometry!

I thought for sure this was on this dumb blog somewhere..but I can't find it...

Hey -- and if anyone has ever updated this ultimate guide to contamination from 2008 -- please let me know!

Got something weird coming off your column? Chances are it's in this thing!

The paper isn't open access so if you can't get to it -- do I ever have good news for you!

Boston College Chemistry Department hosts the supplemental lists. If you use them, please site this amazing work, but you can get the full lists here!


  1. Hi Ben, I've been using UWPR's excel sheet, it looks very similar to the Boston College link you posted with some additional masses and tabs. Here's the link:


    1. There's a nice paper for identification of contaminants using Skyline. Matt

      J Am Soc Mass Spectrom. 2018 Jun;29(6):1327-1330. doi: 10.1007/s13361-018-1940-z. Epub 2018 Apr 17.
      Rapid Assessment of Contaminants and Interferences in Mass Spectrometry Data Using Skyline.

  2. Remember also that there is the MaConDa database of contaminants at and also on @PastelBio's resources page ;-)
