Oxford Instruments Magnetic Resonance : MQR – TD-NMR Research system
- 20MHz TD-NMR research system
- High performance digital spectrometer
- T1, T1ρ, T2, and diffusion measurements
- Pulsed field gradients and VT probe options
- Data analysis options including 2D data sets
- User programmable with open data environment
Introducing the Oxford Instruments Magnetic Resonance : MQR – TD-NMR Research system
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 ρ capability, variable temperature probes,
and advanced data processing including 2D inverse Laplace transforms.
