1913 | Sir Joseph Thomson measures the mass-to-charge ratio of ions with an instrument he called a parabola spectrograph.Today, an instrument that measures the mass-to-charge ratio of charged particles is called a mass spectrometer --- #proteomics #prot-other

Yes, this brings the CDC guidelines for COVID into line with guidelines for RSV and influenza. It's not just that is COVID more severe. The guidelines for RSV and influenza are not right either. We need universal paid sick leave, not permission to return to work while still contagious.

Americans may be advised that it’s safe to return to regular routines after one day without a fever.

Parag got many of us on board and made data accessibility a true community project. Involving labs like Dave Tabb's, companies like Insilicos, and our lab. We should be building on each others development efforts. From the start, Skyline has been part of the Proteowizard repo by design.

Not many realize how hard it was to get the six major instrument vendors to make their data files accessible. Parag definitely pushed for it early. When we ran into complexities of establishing a legal entity to sign the agreements, he established the Proteowizard Software Foundation.

That's great to know. Shocked that a fused silica emitter could contain this sort of bgrd. When we make our own column, the 'tip' is washed with methanol. Most of this is to remove the polyimide coating. Surprised a commercial vendor that makes an emitter doesn't have an extensive wash process.

Just be careful with what you wash your hands with. In general, if you can smell it, the mass spec can detect it. That old thread might have been from our lab. Michael Bereman was the one who caught the problem in our lab but was horrified when he traced it to his own deodorant.

We've experienced this only when there were selected deodorants or antiperspirants worn in the lab. I can assure you that Old Spice is a nightmare in an MS lab. We spent months tracking it down in the past. Here's the paper that gave us the idea to consider it. pubs.acs.org/doi/10.1021/...
