UMass Amherst Nuclear Magnetic Resonance Facility
Main description
The High-Field NMR Facility at the University of Massachusetts Amherst is an interdepartmental facility, open to researchers of the Five Colleges Consortium (UMass Amherst, Smith, Mt. Holyoke, Amherst and Hampshire Colleges) and surrounding industries. It supports research programs of twenty groups in the areas of chemical synthesis, polymer chemistry, materials science, and natural products.
The facility oversees five NMR spectrometers. Two of them (DPX300 and Avance400) are public-access spectrometers for the research needs of 200 users and the teaching needs of graduate and undergraduate students from all science and engineering majors. Three additional spectrometers are available for advanced applications. The Avance600 spectrometer is equipped with a cryoprobe and capable of triple resonance and gradient experiments, while the DSX300 and Infinity300 are wide bore solid-state spectrometers which are equipped for triple resonance, high-speed magic angle spinning, and wideline experiments. The spectrometers are Ethernet-linked to a number of Silicon Graphics and Windows computers for data analysis, computation, and manipulation of three-dimensional structures.
Instruments
- DPX300. DPX300 is an open-access solution NMR capable of detecting 1H, 13C, 19F, and 31P. It is equipped with z-gradient and a wide variety of multidimensional experiments.
- Avance400. Avance400 is an open-access solution NMR for 1H and broadband heteronuclei (15N to 31P). It is equipped with z-gradient, variable temperature capability, and a wide variety of multidimensional experiments.
- DSX300. Solid-state NMR with X-Y-1H triple resonance. It is equipped with 4mm and 4mm double- and triple-resonance probes, with MAS spinning speed of up to 15 kHz.
- Infinity300. Solid-state NMR with X-19F-1H triple resonance capability.
- Avance600. Restricted-access solution NMR with cryoprobe. Please contact the Director if you have a justification to use.
