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

  1. Peptides
  2. Proteins
  3. Polymers with Low Polydispersity Indexes
  4. Small Organic Molecules

Polymer Characterization

  1. Molecular weight distribution averages (Mn, Mw, Mz) for polymeric systems
  2. Polydispersity index (PDI)
  3. Polymer structure elucidation


  1. 384 spot target plate for high throughput experimentation
  2. Gridless ion reflectron for increased mass resolution and accuracy
  3. High resolution magnifying observation optics with display on PC monitor
  4. Large area target (12cm x 8cm) with exact dimensions of micro titer plate
  5. Pulsed Ion Extraction (PIE) for enhanced detection
