The University of Bergen (UiB), Department of Chemistry, intends to purchase a new high resolution NMR instrument:
1 600-MHz (14.10 T) 54 mm bore NMR instrument with good magnet shielding and a vibration damping system.
The following specifications will be requested:
— At least 3 and preferable 4 or 5 RF synthesizers and channels;
— Z-gradient electronics and probe heads should be equipped with a Z-gradient coil;
— Equipment for variable temperature control;
— A cryogenic inverse double-resonance probe, or preferably an inverse triple-resonance probe or an inverse quadruple-resonance probe. It is desirable that the probes have cryogenically cooled pre-amplifiers;
— Automatic tuning and matching;
— Equipment for automatic sample changes preferably with cooling options;
— Low cryogenic cost (nitrogen and helium consumption, with and without cold probe installed);
— Possible nitrogen and helium level monitoring at the workstation.
Detailed specifications will be given in a regular announcement.
In general UiB requires NMR magnets that can deliver high-quality spectra including long term 2D and 3D experiments. High sensitivity to keep the running time down for low concentration samples is important. High stability and dynamic range is mandatory. Versatile and reliable temperature regulation for the samples is necessary.
It is important that the supplier can offer sample exchanger for the high resolution NMR instrument.
The equipment must be user-friendly and in addition flexible and come with high functionality in both software and hardware, preferably with options for remote control/operation of the spectrometer. Likewise, the post-processing abilities of the acquired data and quality of software packages are important.
It is important that the selected instrument make it possible for us to arrive at an optimal overall solution. Our focus will be that the total instrument package is up to the standards that we need in our laboratories.
