Nuclear Magnetic Resonance Spectroscopy

The DPX 300

The Honeychuck group is the major user of the DPX 300, and keeps it in running order with the help of our departmental technician Imrana Islam. We make routine use of NMR in much of our work, observing nuclei including ¹H, ¹³C, and ¹⁹F for structural analytical purposes.

The instrument is a Bruker Avance DPX 300, located in Science & Technology I a few feet from many of the department’s research labs. This is a solution phase instrument with 2 probes: a 5 mm QNP four nucleus probe for routine use, and a broadband probe for other nuclei. The instrument controller is a Hewlett Packard workstation running Linux and TopSpin, Bruker’s easily mastered NMR interface software. With a variable temperature unit, dedicated scroll compressor delivering ultra-clean and ultra-dry spinning, VT, and lift air, passive antivibration feet, and a 7.05 T magnet, this instrument serves well the magnetic resonance needs of several groups at GMU.

The DRX 400

Construction on the future home of the DPX 300 and DRX 400 will be complete in January of 2010. At that time both instruments will be relocated to that room, in Science & Technology I. The DRX 400 is a solution phase multiprobe research grade instrument which is currently de-energized pending conclusion of the construction.
