GG-500

DRX-499

GG500 is the newest addition to the walk-on Workhorse instruments.  This console is of the latest technology among all the walk-on low field NMR instruments in the facility i.e.  Bagley 37.   The instrument is paired with an excellent Oxford 500 superconducting magnet with an industry standard vibration isolation system that gives phenomenal lineshape stability and resolution for 1H as well as other X nuclei studies.  This spectrometer sports a user friendly 'Point and Click' IconNMR interface that makes the use of the system a breeze.  This increases throughput and affords optimal use of this wonderful resource.

This instrument is on extended loan from the Drobny group, while DRX-499 handles undergraduate instruction for the term.
