VNMRS 400 MHz NMR Spectrometer
The 400 MHz NMR was originally purchased as a Varian Unity/Inova model in 1994 and was completely upgraded to the Varian VNMRS model in October, 2007 under the NSF Multi-user Grant # 0639199.
The system is complete with robotic sample insertion, automatic tuning and variable temperature accessories. FTS air dryer provides dry air with a dew point of -85oC to the FTS preconditioning sample Cooler. There is an available nitrogen gas source for applications below -85oC. The system is equipped with two probes: a auto-tunable indirect detection 1H{15N-31P} PFG probe and a auto-tunable Dual Broadband 15N-31P {1H} PFG probe optimized for broadband detection. Both probes are compatible with the auto-tuning accessory. The dual broadband probe is the standard probe left on the magnet at all times. Arrangements can be made to change the probe to the indirect detection probe upon request.
