Method of obtaining measurement data

Dear users,

The link to the data store changed on 02/25/2022.

Information about the new address of the CMR data storage was sent to the heads of existing projects.

Up-to-date information about the address of the data storage is posted on our bulletin board located above the table with samples and at the entrance to room 1062 of the CMR.

We do not publish this information here at the request of the IT staff.

New sample changer

The Bruker Avance III 500 MHz instrument is now equipped with an automatic sample changer. The capacity of the new system is 24 samples. The new equipment will significantly optimize the use of the instrument time of one of the most demanded instruments in the Center for Magnetic Resonance.

The new instrument in the CMR

A new NMR spectrometer – Bruker AVANCE 500 NEO was launch at the Center for Magnetic Resonance. The AVANCE NEO represents the next generation in the AVANCE series product line. The AVANCE NEO is based on a ‘transceive’ principle, meaning each NMR channel has both transmit and receive capabilities. So each channel is its own independent spectrometer with the full RF generation, transmission and receive infrastructure.

This architecture provides the greatest flexibility in terms of instrument configuration and multi-channel operation. Multi-receive experiments are easily implemented with this new approach.

The spectrometer will soon be equipped with a broadband
CryoProbe™ Prodigy (BBO), which will reduce the time of long heteronuclear NMR experiments by several times and significantly
reduce the waiting time for spectral data by users.

The cryomagnet of the spectrometer is equipped with an air suspension system that reduces vibrations and, as a result, significantly improves spectrum quality.

The spectrometer operates under the latest version of TopSpin 4 software, which implements the latest advances in spectral data processing and analysis.

CMR operation under constraints

Dear customers, the Center for Magnetic Resonance, like other departments of St. Petersburg State University, is gradually getting out of the restrictions associated with the spread of the new coronavirus infection (COVID-19). You can obtain up-to-date information on the restrictions still in force by referring to the corresponding orders published in the documents section (in Russian) on the SPbU website.
