AV-800

This is the highest field instrument available in the facility, which is geared for handling either very low concentration samples or those with very high molecular weights. All the routine NMR spectroscopy are also possible, of course. The instrument is based on the latest model BRUKER AVANCE III console and drives a cryogencially cooled probehead that has a 1H sensitivity that is unrivaled in any other facility instrument. The detectability for 1H can be as low as 100 microM with this spectrometer.
