About the MALDI-TOF


  • Mass Range: m/z 500-1,000,000
  • Resolution (m/Δm): 5,000 (linear mode), 20,000 (reflectron mode)
  • Accuracy: 200 ppm (linear mode), 10 ppm (reflectron mode)
  • 337 nm Laser
  • Ionization Source: Matrix-assisted laser desorption ionization (MALDI)
  • Mass Analyzer: Time of flight (TOF)

Common Applications

  • Characterization of biopolymers (proteins, protein digests and oligonucleotides)
  • Organometallic complexes
  • Some synthetic polymers
  • Molecules that photoionize upon radiation by 337 nm laser
  • Labile molecules
