Bruker Avance III HD 800 (2015/2015)

General Information

Nuclear Magnetic Resonance (NMR) spectroscopy is a non-destructive method to observe the chemical and physical properties of atoms. The method is mainly used to investigate the properties of organic molecules, though it can be applied to any kind of sample that contains nuclei with a spin. 

The Bruker Avance III 800 MHz NMR spectrometer can perform high speed NMR spectroscopy.

Key Features
  • High speed NMR spectroscopy.
  • Longer measurements.
  • High sensitivity.
  • Dual-receiver system enables simultaneous detection of two nuclei. Allows for instance parallel 1H / 19F experiments.
  • A helium cooled TCI cryoprobe for 1H/13C/15N detection.
  • Automated tuning & matching for the probe
  • Fridge-cooled carousel for 24 samples
  • Digital receivers. Digital receiver unit (DRU) contains real time digital filters which compress data on the fly and in real time. Large bandwidth data filtering (up to 5 MHz).
