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:http://www.proteomicsresource.washington.edu/docs/protocols05/UWPR_CommonMassSpecContaminants.xlsCheers,Peter
There's a nice paper for identification of contaminants using Skyline. MattJ 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.
Remember also that there is the MaConDa database of contaminants at http://www.maconda.bham.ac.uk/ and also on @PastelBio's resources page http://www.pastelbioscience.co.uk/resources/databases.html ;-)
