Kronus GC/TOF-MS (Gas Chromatography - Time of Flight - Mass spectrometry) GCMS

Excellence in Mass Spectrometry

MALDI-MS The “LaserToF” range of MALDI-ToF instruments
GC-MS The “Kronus” range of continuous beam orthogonal ToF analysers for GC-MS and GCxGC-MS.
SIMS The award winning “MiniSIMS” designed for the cost effective surface and interface analysis of materials.

Kronus GC TOF-MS

The first of a new generation of GCMS instrumentation, Kronus represents a new concept in design of Time of Flight analyser combined with a fully integrated gas chromatograph in a compact benchtop instrument. The mass spectrometer is based on a novel combination of energy filter preceding a Time of Flight analyser to give the best possible sensitivity and dynamic range in all GCMS ionisation modes. This revolutionary concept brings all the advantages of time of flight technology to GCMS in a small affordable package.

Gas Chromatograph

This offers outstanding performance and quality. Accurate temperature control and fast cool down are important features of this purpose built system. A complete range of detector systems is also available. Injection via a patented cool septa injector gives low background noise and enhanced sample transfer resulting in improved GC-MS operation.

Mass Spectrometer

GCMS Ion Sources. These dedicated plug-in ion sources offer unmatched sensitivity in EI, with optional positive and negative CI.
Quick change between EI and CI
Easy source access and plug-in design of the source and optics assembly, ensure fast and easy maintenance without the use of special tools
