Richard D. Smith

Excited to announce that the Purdue Board of Trustees has approved my promotion to Associate Professor, effective this August. Thank you to friends, collaborators, #teammassspec members for your incredible support of my career so far!! purdue.edu/newsroom/purdu…

My last day at PNNL before retirement. A great place to have spent 47+ years with a career centered around MS, separations, and their many applications. May engage in a few consulting etc. activities, but VERY selectively….and I guess at least one more Annual ASMS meeting!

Space charge can be our friend; ion separations in large ion populations as a basis for e.g., industrial scale ion processes. Accumulation of Large Ion Populations with High Ion Densities and Effects Due to Space Charge in SLIM IMS-MS pubs.acs.org/doi/10.1021/ja…

Curious about what SLIM ion mobility can do for your separations?? Be on the lookout for an upcoming paper from Selena, showing the benefits of @MobilionSystems SLIM technology for clinical analysis including Vitamin D metabolites!

A detailed computational dive into the Role of Ion Rotation in Ion Mobility: Ultrahigh-Precision Prediction of Ion Mobility Dependence on Ion Mass Distribution and Translational to Rotational Energy Transfer. Bottom line: rotation matters. pubs.acs.org/doi/10.1021/ac…

Terrific session on ion activation/dissociation organized by @SLIM_technology honoring the career of Jean Futrell and celebrating his 90th birthday in 2023. Wonderful talks, highlighted by Dick Smith and @LabLaskin . Great to see all of Jean’s friends @asmsnews #ASMS2023

Happy to share our new #python tool LipidOz for determining lipid double bond positions from OzID data. #opensource #automation #deeplearning Feel free to share and test it out! @CommsChem #TeamMassSpec disq.us/t/4fub0vk

A blast from the past; a Perspective/Account stimulated by all the exciting progress being made by CDMS Individual Ion measurements. Large Individual Ion FTICR Measurements from the Mid-1990s Using Reactions for Charge Determination Mass Spectrometry pubs.acs.org/doi/10.1021/ja…

One reason I wrote this was the mostly forgotten and unexpected observation of charge state increases; something unlikely to be observed with a population of ions. Individuals are hardly ever avarage! pubs.acs.org/doi/10.1021/ja…

Seeing the book's cover reminds me of the original artwork created by Marianne Wendeborn. Derived from the first intact analysis of a virus with mass spectrometry. Nice memories. onlinelibrary.wiley.com/doi/10.1002/15…

Don't miss out on @Pittcon March 18-22. Join us 3/22 2:45-3:20pm to hear from @ChouinardLab @clemsonuniv as they share their innovative insights on High-Resolution Ion Mobility Approaches for Small Molecule Analysis. Symposium details: hubs.ly/Q01HqhWj0 #TeamMassSpec #SLIM

A truly impressive work from the Rizzo Laboratory using a SLIM-based multistage IMS-CID technique combined with cryogenic IR spectroscopy for glycan analysis pubs.acs.org/doi/10.1021/ja…
