Comparison between triple quadrupole, time of flight and hybrid ...

WebbThe quadrupole can spend no more than 1 second accumulating signal for each mass-to-charge ratio, while the TOF accumulates the full ten seconds of signal for each m/Q. It’s clear that the TOF will measure a higher number of counts for each m/Q and therefore have a higher sensitivity over the 10 second period. WebbThe ultra-high mass selection quadrupole can be used to isolate the 4 MDa HBV particle at m/z 25,000 for subsequent fragmentation. The Q Exactive UHMR instrument confidently detects ions with m/z values up to 80,000 m/z. Here, the tandem MS spectrum of the 4 MDa HBV capsids at 300 eV HCD energy shows sequential ejection of up to 17 out of the … Webb1 jan. 2012 · When the first model of an Orbitrap-based mass spectrometer (Thermo's LTQ-Orbitrap) was launched on the market in 2005, it constituted a major technological … stewart hatch
