Bench-top EPR-5000 spectrometer part of the University Science and Creative Park

What does an inconspicuous box weighing 40 kg hide? It is a modern table spectrometer of electron paramagnetic resonance (EPR) filled with modern technologies.

EPR (Electron Paramagnetic Resonance) is a spectroscopic method and technique that detects free (unpaired) electrons found in organic radicals and transition metal complexes resp. lanthanides. It also detects defects in materials. It is widely used in the detection and analysis of dangerous free radicals.

Yevgeny Zavojski discovered and built this magnetic resonance technique in Kazan in 1944 (nominated for the Nobel Prize 22 times).

Bench-top EPR-5000 spectrometer (Bruker / Magnettech) is a powerful instrument with high sensitivity and reliability. It is used to detect electron levels in paramagnetic complex compounds. It replaces older models of hall-type spectrometers with a massive magnet wound from copper material. Its operation is very simple, convenient ("user friedly") and inexpensive. It is connected to a traditional electrical outlet.

The EPR spectrometer naturally complements another resonance technique - nuclear magnetic resonance (NMR). Both spectrometers are installed in the Analytical and Diagnostic Center of the Faculty of Natural Sciences in Špačince as part of the University Science and Creative Park.

The spectrometer will be used in solving scientific projects and in final master's and doctoral theses. It will be used mainly by a top scientific team consisting of prof. R. Boča, (Scientist of the year 2012 in Slovak Republic), prof. J. Titiš, PhD., assoc. prof. D. Valigura and Dr. C. Rajnák (young scientist of the yer 2019 in Slovak republic).
