Aurora Low Frequency NMR Spectrometer

The Aurora is a cost effective low field NMR research spectrometer designed to work in the 0 kHz to 100 kHz frequency range.

The Aurora system is particularly useful in applications such as hyper-polarised gas NMR, where low magnetic field strengths result in NMR frequencies outside the operating range of most NMR spectrometers. The Aurora uses direct detection technology to avoid frequency band filtering, allowing detection of NMR signals all the way down to DC.

The affordable Aurora can be deployed for applications such as monitoring the production of hyper-polarised gas via NMR. Hyper-polarised gas NMR provides sufficient signal strength at much lower NMR frequencies than those used for thermally polarised NMR.

All the normal pulse parameters can be varied, and the experimental results analyzed, with the Prospa macro language. For example, experiments that use low flip angle excitation to preserve spin polarisation can be performed over many hours, with the data being stored for later analysis in a multi-dimensional matrix.

The Aurora includes a built in low frequency transmitter amplifier and receiver preamplifier; no additional equipment is required. The system connects to a PC using a USB interface.
