Spotted at Ion Opticks booth🤣 yeah, I am at #HUPO2025. Let’s chat :)

Congrats! and good luck!:)

At Uni, at Mike Gorshkov lab. First good practical skills I gained in Denmark, at SDU. Then reading articles helped a lot:) And I am still learning:)

I just wanted to share some painful experience related to weird mass accuracy, that we faced in the past, and which took us quite some time to investigate:) Maybe it will be helpful for someone else:)

However, if data with different CVs and for each CV mass acc differs, the distribution will be bimodal. So the correction will be either suboptimal or need to be done separately for each CV.

Oh, yeah:) let’s me paraphrase. My example isn’t the cause of this strange behaviour. It’s additional layer, which can cause similar strange behaviour:) for this data, one can nicely correct mass shifts.

I’m a bit surprised that somebody remembers this article:) thank you:)

It's also good to check mass acc for different Compensation Voltages separately. We also once had raw files, where mass acc was shifted only for one CV, and completely ok for the other.

I guess you can find the right answer in the author list😀 in this case, the intuition won't fail for sure😀

Finally, it is out!:) #SCP #Astral #massspectromentry www.nature.com/articles/s41...
