Bruker AVANCE NEO 500 MHz Three channel NMR spectrometer
This instrument provides broad analytical capabilities for solving non-routine problems related to physics and chemistry of condensed phase. Biomolecules (proteins, enzymes) and complicated organic molecules (polymers, natural compounds, steroids) could be studied.
The spectrometer is equipped with a broadband direct observation probe that allows one to measure NMR spectra on 1H, 19F, and in the range from 31P to 109Ag, as well as to study diffusion processes in liquid media.
The spectrometer is equipped with a Prodigy (BBO) broadband cryoprobe, which allows several times to reduce the time of lengthy heteronuclear NMR experiments and significantly reduces the waiting time for spectral data by users.
The most modern modification of the radio frequency unit – 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 three-channel arrangement of the new device makes it possible to carry out the widest range of modern NMR studies.
The spectrometer is controlled by the latest version TopSpin 4 software, which opens up the possibility of applying the latest achievements in the processing and analysis of spectral data.

Bruker Elexsys E580 EPR spectrometer is a setup working at 9 400 MHz, (3.2 cm wavelength, X-band) suited for studies of paramagnetic centers (PC) in solids, liquids, solutions and gases. Measured spectroscopic characteristics are g-factors, lineshapes and relaxation parameters in a wide temperature range. Experimental complex is capable to determine electronic state of PCs, their location in a crystal lattice, crystal field anisotropy and super-fine interactions between unpaired electrons and nuclei. It is possible to study isotopic composition of PCs and their interaction with adjacent ions, to investigate the presence and type of magnetic interactions etc. Spectrometer is equipped with additional modules allowing one to conduct ENDOR (Electron Nuclear DOuble Resonance) and TRIPLE experiments in order to investigate direct and indirect exchange interactions.
