Benchtop Nuclear Magnetic Resonance System

The University of Huddersfield seeks to purchase a Benchtop NMR system for optically generated hyperpolarization studies.

A benchtop nuclear magnetic resonance (NMR) system is required for research into a new method of signal enhancement in NMR spectroscopy, which is dependent upon optical illumination of the liquid sample prior to measurement. The research project will include an investigation of the effects of illumination at different magnetic field strengths prior to transfer to the detection field.

The key requirement of the system is therefore that optical access must be possible to illuminate the sample at a variable height within the magnet bore where the static magnetic field is ≥ 350 mT, and that rapid flow from the illumination region to the NMR detection coil is possible (transfer time to be short compared to T1, maximum transfer time 0.5 s). Minimum permissible clearance around sample tubing in magnet bore for insertion of fibre optics is 6 mm radially.

NMR spectrometer specifications:

1H and 13C detection at a magnetic field of around 1 T (approx. 43 MHz and 11 MHz NMR frequencies)

High 1H sensitivity (at least 50:1 in single scan on 1% ethyl benzene or similar) Linewidth 90% 400-700 nm) material (e.g. glass or quartz) in the accessible illumination region (≥ 350 mT) within the magnet bore

Computer control of sample flow for synchronisation with user-defined NMR pulse programmes or reaction monitoring scripts

System requirements:

Cryogen-free system

No external cooling water needed

Computing:

Spectrometer to be supplied with control computer and all standard peripherals (monitor, keyboard, mouse); minimum hard ...
