Article Snippet: EPR signals were recorded from paramagnetic DNICs at room temperature or 150 K using an X-Band EPR spectrometer (Bruker, Billerica, MA).Unpaired electronics are found in transition metals, reactive intermediates, photo-activated states, defects in materials, food stuffs and so on.ĮPR is much more sensitive than NMR and techniques such as spin trapping or spin labelling can be used to broaden the application of EPR For instance, microwave devices in the 9 GHz frequency region (X-band) were used in. It is also called ESR, electron spin resonance, when used for organic radicals. paramagnetic resonance spectrometer (HF-EPR), a system of vacuum. The EPR was upgraded to EMXplus from ECS in 2014 with all new electronics.ĮPR (Electron Paramagnetic Resonance) is a spectroscopic technique that detects unpaired electrons. Resonator for aqueous samples (ER4123D), with optical opening for light irradiation and TPX capillaries for N2/O2 relaxation studies.Good for dosimetry, detecting free radicals, radical trapping, high spin metal complexes.Liquid nitrogen temperature control from 80 to 500 K. ![]() Liquid helium temperature control to under 4 K. ![]()
