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.

3-axis pulsed field gradients option

Allows MRI.

Overview and Options

Overview

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.
