  • Hybrid Mass Spectrometer (Ion Trap and Orbitrap Analyser)
  • Linear Ion Trap capable of multi stage MS fragmentation
  • C-Trap capable of accumulating specified lock mass ion(s) for the calibration
  • Resolution 60,000 at m/z 400 at a scan rate of 1 Hz
  • Ideal for multi stage MS, SIM and data dependent acquisition

Perform a range of applications from protein identification, to biomarker discovery, de novo sequencing and metabolite profiling, with confidence.

Protein Identification

  • High mass accuracy lowers false positive rates
  • Parallel acquisition mode optimizes productivity
  • High MS and MS/MS sensitivity, wide dynamic range and fast cycle times increase protein identifications

Biomarker Discovery

  • HCD collision cell provides high fragmentation efficiency combined with high sensitivity for the reporter and fragment ions of the peptide sequence
  • Reliable identification and quantification in one experiment

De novo Sequencing

  • High mass accuracy and high resolution leads to high confidence de novo sequencing results
  • Multiple collision modes (CID and HCD) provide comprehensive structural information

Metabolite Profiling and Identification

  • High mass accuracy, sensitivity, and dynamic range enable reliable profiling of low-abundance metabolites in complex mixtures
  • MSn spectral tree fingerprints distinguish between isobaric compounds
