Voyager STR-DE MALDI-TOF-MS (Applied Biosystems)

Instrument Features

• 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.
• 3-meter effective flight path, reflector mode and patented Delayed Extraction® (DE) technology
• 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 for more structural information
• Fully automated acquisition and processing of data for higher throughput
