Opći opis
On the platform of NMR magnet Varian 7300 scientists from the Laboratory for magnetic resonances RBI put together an X-band EPR spectrometer in the continuous (CW) working mode. It has been financed from the own project resources: MZO (MZO (dr. sc. Boris Rakvin), HrZZ project-SPES (dr. sc. Marina Ilakovac Kveder) and EU structural funds project AVACS (coordinator for RBI is dr. sc. Marina Ilakovac Kveder). The value of the instrument is more than 1.500.000,00 kn (the last purchase, the magnet power supply, costed about 800.000,00 kn) as the spectrometer is equipped beside the magnet also with the microwave bridge, the source of microwaves, cryostat, allowing liquid helium temperature, as well as with various resonator cavities. This spectrometer is unique in Croatia as it allows to gain magnet induction of 1.9 T and has large magnetic sweep, especially important for studying metal centres in (bio)materials. These characteristics secure the possibility to upgrade the spectrometer to higher EPR frequencies in the future, like Q-band, which is a standard in the characterization of materials.

Opis usluge
Paramagnetic centres in materials are detected either as endogenous molecules (e.g. coordinated metal centres like copper, vanadium etc..) or they are introduced via ionizing radiation, in terms of spin labels, spin probes or spin traps. From the EPR signal one is capable of deducing about the structure and dynamics of the environment in which unpaired electron spin is located.

Princip rada i mjerna tehnika
In EPR spectroscopy one detects the absorption of microwave radiation when the energy of microwaves equals the energy splitting between the energy levels of unpaired electron spin in the magnetic field.

Detaljne tehničke karakteristike
EPR spectrometer has been put together by the efforts of the members of the Laboratory for magnetic resonances, RBI, using the platform of Varian 7300 NMR magnet. It is an CW EPR spectrometer working in the X-band, but it is possible to upgrade it in the future to the Q-band frequency region.
