The AV400 NMR spectrometer is equipped with a cryogenic QNP (1H, 13C, 19F, and 31P) probe. The sensitivity of 13C, 19F, and 31P of this cold-probe is 3 to 4 times better than a conventional QNP probe, which allows a rapid turn-around for a routine 13C experiment. The AV400 NMR also has a sample changer which accepts sample submission 24/7. The day-queue is reserved for a quick turn-around analysis for experiments such as 1H, 13C, and 2D COSY. The night-queue is for experiments that require one or more hours of instrument time such as 13C NMR for diluted samples and two-dimensional experiments (HMQC, HSQC, NOESY).
The data acquired on the AV400 NMR spectrometer is automatically transfered to an NMR data server. Three workstation located in 045 BRL are used to access NMR data acquired on AV400 NMR. NMR training on instrument automation, sample loading/unloading, data processing, and magnet laboratory safety is available for all researchers at the University of Delaware.
No web-reservation is required for the use of this instrument.
The AV400 NMR is an NSF CRIF funded spectrometer and it is Cyber-enabled for remote control and access. Academic users of nearby colleges and high schools are welcome to use this spectrometer. Please contact NMR facilities manager for details.
