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 drives a cryogenically 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 µM with this spectrometer.
