We have a free (already paid for) space available at this year's Ardgour Symposium! More details here - www.emsg-ardgour.site If you can get yourself to Aberdeen on the 20th August, then you could be enjoying a week of mass spec and related discussions, in the Highlands and with a free bar! #teammassspec #massspec #lipidomics #metabolomics #proteomics #ionization

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.

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.

We had an excellent #CompMS session at the #ISMBECCB2023 conference last week.

Many thanks to keynote speakers @lgoracci01@twitter.com, @RenardLab@twitter.com, and @tomas_pluskal@twitter.com; all selected speakers; and poster presenters for showcasing the latest computational advances in mass spectrometry, with applications across #proteomics, #metabolomics, #lipidomics, and more.

RT @: Folks! We have created a survey to better understand users' experience with OpenMS. The survey is short, and we would love to hear your opinions on what's good and bad! Please share your thoughts

We’ve looked at the last 60 years of evidence on #sebum research so that you don’t have to guess what works well for sebum #metabolomics and #lipidomics study! A tremendous effort by Caroline and Julia is now available to read in @metabolomics rdcu.be/c8qdH

After 10+ years working with #metabolomics mass-spectrometry data, you would think I wouldn't be surprised any more.

However, I'm surprised every time when a method or tool uses non-log-transformed abundances into a standard t-test or another semi-normal distribution assuming statistical framework. 🤦‍♂️

Seriously, we need more statistically minded people in #metabolomics / #lipidomics.

There are great #lipidomics databases for researchers. Why not have a look at @lipidmaps?

However from time to time we still need to put on our thinking caps to decipher lipids in biological organisms: https://journals.asm.org/doi/10.1128/AEM.02157-18 #LipidomicsTakeover @MaryKDoherty

Our targeted #lipidomics methods analyse specific families of lipids using both #LCMS and #GCMS. Adding internal standards during sample preparation permits quantitative analysis of lipid(s) of interest by mass spectrometry. #LipidomicsTakeover

RT @polyomics
In a recent study we used global #lipidomics to investigate disturbances in #ceramide metabolism in #Lewy body disorders. #LipidomicsTakeover https://link.springer.com/article/10.1007/s00401-021-02367-3 @nubiosciences @wcmtm_ugot @ThinkUHI

Our global #lipidomics method uses high-resolution mass spectrometry to measure populations of lipid molecular species. The data sets are interrogated using #bioinformatics software and statistical tools to determine changes in lipid profiles. #HRMS #LipdiomicsTakeover
