750 MHz 89 mm NMR & MRI/S System (Gainesville)

750 MHz 89 mm NMR & MRI/S System (Gainesville)

This instrument, 750 MHz/89 mm Bruker Avance III HD, is located at the MagLab's AMRIS Facility at the University of Florida in Gainesville.

NMR experiments may be acquired using an Avance III HD spectrometer manufactured by Bruker Bio-Spin operating at a field strength of 17.6 tesla (750 MHz) with an 89mm bore. Spectroscopy data are collected using TopSpin software (version 3.6.1) while imaging data is collected with ParaVision 6.0.1.

The 750 MHz system is suitable for imaging live rodents; mice in either the 30 or 33 mm coils, or small rats (<120 g) for head imaging in the 33 mm coils. A new gradient shielding setup has been implemented to significantly reduce artefacts previously seen from 4G/LTE interference.
