Just in case anyone in #TeamMassSpec is curious, the likely culprit of my 248.9 m/z ion from this thread: https://mstdn.science/@sarahehancock/110818463525422168 is free cyanide reacting with the gold seals of the HPLC pump. I will have to try a few different brands of solvent to see if I can ameliorate this issue.

Attached: 1 image Hey #TeamMassSpec, I'm having issues with a contaminant ion @ 248.9 m/z in -ve ion mode when running 90% ACN 10 mM AmOAc at pH 9. Found a thread on research gate suggesting it comes from the ACN but have tried two brands now with no joy. Has anyone else had this problem? Research gate link: https://researchgate.net/post/What-is-this-contaminant-with-m-z-2489718 ACN brands tried: Fisher Sci Optima, Supelco LiChroSolv. LiChroSolv has a lot less of it than Fisher Sci. #metabolomics #lipidomics #massspectrometry #massspec

Hey #TeamMassSpec, I'm looking for recommendations for sealing foil/film for 96-well microtiter plates for use in an autosampler. Would prefer something that doesn't require heat sealing. Application is #lipidomics & #metabolomics, samples are typically in methanol or acetonitrile or both.
