Prof. Dr. Thomas J. J. Müller, together with a large number of co-applicants for CeMSA@HHU, has acquired a new 600 MHz NMR spectrometer as a large-scale research device from the DFG in accordance with Article 91b of the Basic Law. This device is now being put into operation.
It is a modern 600 MHz spectrometer with the latest console technology (neo) and the latest magnet technology (evo).
The device is equipped with four sample heads.
1. cryo sample head: This sample head serves as a standard sample head and has a considerably higher sensitivity than the standard sample head on the old spectrometer thanks to the cryo technology (measuring coils and preamplifier are cooled with liquid nitrogen). Nevertheless, the measuring time in the input phase is calculated in the same way as on the old 600 MHz spectrometer.
In principle, all measurements are possible on this device that were also possible on the old 600 MHz device. However, not all experiments have been set up and tested yet.
NUS technology: NUS (non-uniform sampling) allows the measurement of 2D NMR spectra with significantly increased resolution, slightly increased measurement time and a low loss of signal-to-noise ratio. This technology will soon be implemented on both 600 MHz spectrometers, but is not yet available. We will inform you when this technology is available.
2. special sample head fluorine: This sample head allows the simultaneous decoupling of 1H and 19F and furthermore 1H-19F correlation experiments. The corresponding experiments still have to be established here. This sample head is available for special measurements every 2 to 3 months after consultation.
3. sample head with extended measuring range (not yet handed over): This sample head allows the measurement of nuclei with low γ (low frequencies) that were previously inaccessible.
4. HRMS sample head (not yet delivered): For measurements in viscous media.
The sample delivery is at the same location as for the old spectrometers.
