Lab Discription

This NMR laboratory is part of the Chemical Instrumentation Facility located in the Department of Chemistry of Iowa State University. The facility is partially funded by National Science Foundation and the Dean's office of ISU Science and Humanities. Although the primary users of the NMR facility are from the academic community within the University, the lab is open to researchers in other educational institutions and industry. The goal of the laboratory is to provide state-of-the-art NMR instrumentation for scientists in all possible research areas. The facility is housed in room 1708, Gilman Hall on the ISU campus.

The laboratory is equipped with four NMR instruments capable of handling a wide range of nuclei and techniques in both solution and solid states.

Bruker DRX-400 Spectrometer

This 400 MHz narrow bore instrument is equipped with the most modern capabilities available for solution NMR, including pulse-field-gradient (PFG), four channels, shaped pulse, digital filtering. Two 5 mm PFG probes, one is triple resonance inverse probe with 2H/31P/1H/BB channels and the other is normal geometry probe with 2H/1H/BB channels, are capable of handling the full range of nuclei, including fluorine. This instrument is principally used for multi-dimensional or other complex experiments, or those routing experiments requiring higher sensitivity.

Varian VXR-300 Spectrometer

This narrow bore instrument, configured with a 5 mm switchable probe, is designed as a walk-on instrument for routine 1H/13C observation. Users have the maximum of 10 minutes to use the instrument during primetime (8:00am-11:00pm weekdays, 8:00am-5:00pm weekends). For those experiments requiring longer time, users may reserve blocks of time at night in one week advance.

Bruker MSL-300 Spectrometer

This wide bore instrument is capable of doing both solution and solid experiments. The instrument is equipped with six solution probes (5mm 1H, 10mm 1H/13C, 10mm 1H/BB, 10mm 1H/19F, 10mm 1H/BB, and 20mm 1H/BB) and three MAS probes (1H, 1H/44-122MHz, and 1H/30-80MHz) for high resolution solid NMR. This instrument is designed for basic long-term experiments, such as kinetics, low-concentration measurements, and solid NMR.

Bruker AC-200 Spectrometer

This 200 MHz narrow bore instrument is equipped with two broadband switchable probes (5mm 1H/BB, 10mm 1H/BB) capable of measuring a wide range of nuclei, including 31P, 13C, 2H, 17O, 15N, 14N, and 29Si. Similar to the MSL-300, the AC-200 is designed for the users who need a large block of experiment time.

All NMR instruments have the variable temperature capability.
