• fragments
  • The fragments are then accelerated out of the collision cell and enter Q3 which scans through the mass range, analyzing the resulting fragments (as they hit a detector). (wikipedia.org)
  • method
  • In contrast, our existing method, which uses a nominal mass quadrupole linear ion trap instrument, collects targeted data on a predefined set of compounds. (aacc.org)
  • corresponds
  • Tandem MS was necessary for resolving complications presented by the fact that (NeuGc:Fuc) corresponds to the exact mass of (NeuAc:Hex). (nih.gov)
  • data
  • And, importantly, how does this compare to nominal mass instruments that collect data in a targeted manner? (aacc.org)
  • Deconvoluted CID data for (A) a high mannose N-glycan with m/z 1235.45 corresponding in mass to [GlcNAc 2 +Man 5 +H] +1 . (nih.gov)
  • detector
  • High-resolution instruments are usually operated in an untargeted manner, which means that accurate mass information is collected on every ion that reaches the detector. (aacc.org)
  • In a product ion scan, a precursor ion is selected in the first stage, allowed to fragment and then all resultant masses are scanned in the second mass analyzer and detected in the detector that is positioned after the second mass analyzer. (wikipedia.org)
  • modes
  • When tandem MS is performed with an in space design, the instrument must operate in one of a variety of modes. (wikipedia.org)
