NMRFAM “Dexter” AVIII-600I

Bruker 600IDexter is a Bruker Instruments AVIII-600 Avance console, 14.1 T standard bore magnet NMR spectrometer. This instrument is equipped with a cryogenic probe.

Console Capabilities

The console of dexter is equipped with 4 channels and 4 amplifiers. The four channels are capable of generating hard and shaped pulses over any nucleus. The four amplifiers consist of three linear amps covering the x-nucleus frequencies up to thalium and a cluster of three amps for proton/fluorine.

The console also has Accustar II gradient amplifiers which are extremely linear, providing up to 50 g/cm for the gradients in the spectroscopy probe.

The controlling computer is HP linux (Centos 5.5). The combination of console and computer should be capable of executing any desired multi-dimensional experiment, with the only limits being the type of nuclei observed.

Available Probes

  • The 5 mm TXI, cryoprobe is the only probe used on this spectrometer.


The base rate for time on this machine is $8.00/hour for publishable work and $250/hour for proprietary work.
