Excited to see this published in JPR. For years I've wanted a simple way to standardize the signal between instruments. We use the precision of an intraspectrum ratio to assess the relationship between the reported signal and the number of ions. pubs.acs.org/doi/10.1021/...
Evaluation of a Prototype Orbitrap Astral Zoom Mass Spectrometer for Quantitative Proteomics─Beyond Identification Lists
Mass spectrometry instrumentation continues to evolve rapidly, yet quantifying these advances beyond conventional peptide and protein detections remains challenging. Here, we evaluate a modified Orbit...

New Preprint ... This was a bit different of a project than what we normally do for hardware comparisons. I think there is a lot of potential in the methods mentioned here for calibrating the instrument response to a common scale. Nice work by @chrhsu.bsky.social!
