This spectrometer is suited for the measurements of 1D, 2D and 3D NMR spectra of liquids and solutions. The equipment provides a broad range of analytical capabilities to solve non-routine problems from fields of chemistry and physics of condensed phase. Biomolecules (proteins, enzymes) and complicated organic molecules (polymers, natural compounds, steroids) could be studied.

  • • Long measurements at low temperature (down to 110 K).
  • • Three-channel architecture (from 1H to 109Ag).
  • • Diffusion measurements at temperatures up to 470 K.
  • • Planned: combined NMR/UV-vis spectroscopy.
  • • Planned: measurements in liquefied gases as solvents.

This NMR spectrometer is designed to study samples in solid state: crystallines, powders, weakly ordered materials, gels, liquid crystals, amorphous compounds, nanostructures (zeolites, silicates) etc. Wide bore of the magnet and advanced set of probes allows one to study diffusion processes, obtain micro-tomographic images, record high resolution spectra with magic angle spinning etc.

  • • Long low- and high-temperature measurements (from 130 to 870 K).
  • • Microtomography (with small animal heartbeat and pulse monitoring unit).
  • • Magic angle spinning up to 24 kHz.
  • • Diffusion measurements (gradients up to 3000 G/cm).
  • • Planned: studies of monocrystals.

These spectrometers are dedicated to perform routine measurements of 1D and 2D NMR spectra. They cover significant portion of demands for a fast-analysis of composition and purity of chemical compounds and reaction kinetics studies, allowing one to investigate final and intermediate products of chemical reactions. The measurement procedure is partially automated.

  • • Direct and inverse detection probes.
  • • Observed nuclei range – from 1H to 109Ag.
  • • Possible 1H{19F} and 19F{1H} measurements.
  • • Possible 2H{19F} measurements.
  • • Temperature range – from 110 to 430 K.

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.
