Thermo Scientific LTQ Orbitrap Velos
The Thermo Scientific LTQ Obitrap Velos provides exact mass measurements (m/z 50-4000) with resolution of >60,000 and mass accuracy of <3 ppm, or 1 ppm with the use of lockmass.
The multiple fragmentation techniques, high collision dissociation(HCD) and collision induced dissociation (CID), enable complete structural information to be obtained through MS and MSn analysis.
