Somebody told me about this the other day. I forget who, but then I found it in my LinkedIn stream. This is a robotic double nanoLC source with a ton of cool features including the ability to pop one column out while the other is running. There is actually a setup in the PDF document that shows 3 nano-emitters set up for instruments that can tune or calibrate (or seemlessly switch to direct injection for some experiments; quick intact protein masses, maybe!) with direct injection.
