From earlier this year in Forensic Science International: we showed that DART ionization on an Orbitrap can identify wood species using the AccuTOF-DART ForeST database of US Fish & Wildlife. Such databases can be compatible with traps or other instruments www.sciencedirect.com/science/arti...

Interlaboratory and cross-platform accessibility of time-of-flight wood identification database

The mass spectral database of tree species built by US Fish and Wildlife Service has thousands of entries and has been a valuable resource to combat i…

I unironically love Waterworld. It's Mad Max on the ocean, what's not to love?

When you take advantage of oil-change time to replace a slightly leaky pump with a brand new pump that an engineer ordered by mistake and left for free, but the new pump turns out to be a lemon

There are GC-single quads less than a decade old?

Maximize your number attended, or maximize what you get out of the individual conference? The former is a question of money, the latter a question of energy (and money)

Virginia Beach gets its own spot on the mass spec meeting map, courtesy of last week's Harsh-Environment Mass Spectrometry Workshop

It's the oldest *anything* detected by DART-MS. The subject of the previous record was merely thousands of years old

I have a new paper with @iondoctor.bsky.social and other MCI, Carnegie Science, and Calvert Marine Museum colleagues where we analyzed 8 and 10 million year old Ecphora shell membranes. We found chitin and various gastropod specific peptides. www.app.pan.pl/article/item...

I can't understand how the most unusable platform became the most popular.

Wow, there's something to erucamide other than being coated on the interior of every ziplock-type baggie that contaminates my samples?

Tell them you're an early-career researcher until you're 40!

The circumstances matter of course. We had savings, my wife's income, and no kids. I still had gov clearance. The job market in DC metro was not like the Great Recession or today. I paid my own way to ASMS that year, I went to every discussion group meeting, and university library was 2 miles away.

If my Smithsonian unit gets shut down, I am prepared to wait it out as a stay-at-home dad until I get a job in the field locally.

After I was laid off 9 years ago I was out for a few months then had a bad job. But I kept up with literature, stayed in MS discussion group, and waited it out

If you click the link for my new paper, I invite you to read the title, highlights, and abstract that I wrote myself www.sciencedirect.com/science/arti...

Pyrolysis and thermal extraction of polymeric materials with suction-driven, real-time ionization sources and rapid polarity switching, high resolution mass spectrometry

Real-time sampling systems are assembled for analysis of pyrolyzed material using in-line ionization and high resolution mass spectrometry. Two commer…

Publishers don't want you to use AI to generate your manuscript (neither do I, to ne clear) but it's okay for *them* to do it. They want subscription access but they'll give you a free slop summary. You can make Elsevier's AI "reading assistant" smaller on the page but it never goes away

Here is a link to the author version which is open for anyone to read (although ASMS members already have access to IJMS) www.sciencedirect.com/science/arti...

I tried this with SICRIT too, as you can see in the paper. Great signal, but there's no way to stop the carryover from even a 10 microgram pyrolyzed lump. With my NPDPI I just flip a switch and pump it out in 30 seconds

Now online: the latest application for my non-proximate desorption photoionization system. I stuck a dang pyrolysis heater on the front, and it's so fast and clean I can do 4 runs in 8 minutes. The MS alternates polarity so no doubling-up experiments www.sciencedirect.com/science/arti...

Wow, I'm about to have a minimum of seven publications in a calendar year - that will beat my personal best in 2023 when all the covid-delayed stuff came out at once

asher newsome @iondoctor.bsky.social · Aug 23

I thought the mass spec people here were quiet lately, but I just logged onto Twitter for the first time in months and it's a real ghost town there (so be it)

Fun to have visitors from Los Alamos Natl Lab and NC State out after ACS!
