Hopefully you didn't catch my 15 min speed rambling at SCP2021, but one of the things that I tried to emphasize was the value of when an ion actually makes physical contact with the detector of a mass analyzer.
It happens in most hardware, including the long forgotten and often maligned ion trap.
Is it time to revisit this relic of ancient history? There might be an argument here.
This ion trap appears to fair quite well in these comparisons even considering where it is placed within the instrument that they are using. Not that the architecture of a hybrid instrument has anything to do with anything when they accomplished 100% ion transfer efficiency a while back.
