Ultraflex Series II MALDI-TOF Mass Spectrometer

MALDIBruker Daltonics’ Ultraflex Series II Matrix Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) Mass Spectrometer provides absolute mass determination of molecules and macromolecules in the range of 50–1,000,000 Daltons utilizing an all-solid-state Nd:YAG laser with adjustable power and a repetition rate tunable from 1–200 Hz.

Absolute Mass Determination

  • Peptides
  • Proteins
  • Polymers with Low Polydispersity Indexes
  • Small Organic Molecules

Polymer Characterization

  • Molecular weight distribution averages (Mn, Mw, Mz) for polymeric systems
  • Polydispersity index (PDI)
  • Polymer structure elucidation


  • 384 spot target plate for high throughput experimentation
  • Gridless ion reflectron for increased mass resolution and accuracy
  • High resolution magnifying observation optics with display on PC monitor
  • Large area target (12cm x 8cm) with exact dimensions of micro titer plate
  • Pulsed Ion Extraction (PIE) for enhanced detection
