Equipment 6 piece(s)

Vertical MRI scanner
Oxford Instruments

The device is used for routine chemical analysis

0.2 T Permenant Magnet

MARAN DRX-HF console at a proton resonance frequency of 8.5 MHz

Three Techron gradient amplifiers which provided maximum magnetic field gradients of 25.7 G cm-1, 24.7 G cm-1 and 33.7 G cm-1 in the x, y, and z directions, respectively

The RF probe is a homemade vertical solenoid 12 cm in length with a 4.4 cm inner diameter. The RF probe is driven by a 1 kW, BT01000-AlphaS, RF amplifier

Variable Field Magnet
MR Solutions

Used for conducting experiments with variable levels of magnetic field

Cryogen-free variable field superconducting magnet operating at 0.79 T, 1.5 T, and 3 T with 1H resonance frequencies of 33.6 MHz, 63.6 MHz, and 127.8 MHz, respectively

The three RF probes employed are birdcages, 9 cm in length and 5 cm in diameter, driven by a 2 kW, BT02000-AlphaSA, RF amplifier

The gradient coil is driven by GA-300 gradient amplifiers providing maximum gradient strengths of 66.4 G cm-1, 64.9 G cm-1 and 87.8 G cm-1 in the x, y and z directions

The magnet is permanently connected to a 4G superconducting magnet power supply

The magnet can rotate from a vertical to a horizontal orientation.

Vertical MRI Scanner

MRI studies of multiphase flows and transport phenomena

4.8 T Cryomagnetics Magnet

A homemade 3D gradient set (max. gradient strength 72 G/cm)

Proton probes (max inside diameter 2.2 cm)

Horizontal MRI Scanner

Used for MRI studies of transport phenomena in fast flows, fluids in porous media, including oil and gas in rocks, water transport in wood, and various routine  NMR/MRI relaxation, diffusion measurements

2.4 T magnet

Several 3D gradient sets, with the maximum magnetic gradient strength of 30 G/cm, and 1D gradient sets (up to 270 G/cm)

A set of homemade RF probes for various nuclei (1H, 19F, 31P, Li, Na, Cl, etc) with 3.8 cm inside diameter

Proton RF probes with 10 cm inside diameter

NMR instrument
Laplacian LTD

Used for studies of transport phenomena, diffusion, thin films

Shaped permanent magnets generate a strong magnetic field gradient of 1700 G/cm with an easy access to sample.

Surface proton and fluorine RF probes

NMR devices (Multiple)

Used for NMR spin density, displacement, relaxation and diffusion measurements in a variety of samples (food products, wood products, various liquids, elastomers, etc.) 


Can be run either by a Laptop, NMR console or by a Minispec console

Generate NMR signal at 1-3 cm away from the surface of magnet arrays

The stray field is shaped by magnet arrays to have either a well-defined, constant magnetic field gradient through the sensitive volume (a range of gradients from 32 G/cm to 512 G/cm) or to maximize the sensitive volume
