Instrument Features:

  • A high performance Matrix-Assisted Laser Desorption Ionization Time-of-Flight (MALDI-TOF) system which is a proven technology for the MS analysis of both organic and inorganic compounds and biomolecule characterization.
  • With its 3-meter effective flight path, reflector mode and patented Delayed Extraction® (DE) technology, the Voyager is still regarded as the industry standard for superior spectral quality, delivering high resolution, sensitivity, and exceptional mass accuracy.
  • Voyager Version 5 with Data Explorer™ software permits flexible acquisition and data processing in both positive and negative ion modes of operation to characterize complex mixtures and determine molecular weight on sub-picomole samples.
  • Post-source decay (PSD) and collision-induced dissociation (CID) options provide more structural information.
  • Fully automated acquisition and processing of data is possible for higher throughput.
