The MQR is a high performance TD-NMR system designed for applications based on relaxation and/or diffusion measurements. The system includes a high performance digital spectrometer, 20MHz (0.47T) permanent magnet, and a choice of interchangeable 10, 18 and 26mm probes.
20MHz operating frequency
Gives high sensitivity and short deadtimes, to allow short T2 components to be detected.
Rack-mounted electronics unit
Allows future upgrades, for example higher power RF or variable temperature probes.
Bipolar 1-d pulsed field gradients option
Allows high quality measurements of diffusion and profiles.
Range of probe sizes
Users can choose the optimum probe for their sample size, to maximise SNR and minimise measuring time.
Interactive, real-time user interface
Allows users to see results as they happen and make adjustments to optimise parameters.
Advanced data analysis software
Allows 1D or 2D data inversion for detailed analysis of phase components.
The MQR is supplied with the Application Developer software package – a fully integrated development environment that allows users to write pulse sequences, set parameters, run and debug sequences, and visualize the results. Shaped RF and shaped gradient pulses can be included, and calculations can be embedded in the pulse sequences. An editable library of common pulse sequences is provided, as well as a basic data analysis software package that includes simple curve fitting and 1D Inverse Laplace transforms. Additional options include high-strength bipolar pulsed field gradients, T1 rho capability, variable temperature probes, and advanced data analysis including 2D Inverse Laplace transforms.
