Transition metal ions have key enabling features for modern society. Fortunately they can be measured by ESR, being a key enabling technique for development of production processes, standard and research applications. Applications of MS5000 ESR spectrometer reaching from biochemistry, medical application throughout chemical characterisation.

Many but not all transition metal ions are bearing unpaired electrons. The ones with unpaired electrons are ESR-detectable by MS5000 due to the high sensitivity of the ESR spectrometer. In many cases still the detection provides information about the ligand field (high spin or low spin) or the oxidation state of the ion.
Occlusion of the splanchnic circulation followed by reperfu-sion (SAO) results in a severe form of circulatory shock,characterized by severe hypotension, hemoconcentration,intestinal injury and a high mortality rate (Lefer & Lefer,1993; Zimmermann et al., 1993).

Heavy metal EPR spectroscopy is a long known application throughout all miniscope series it is a modern application for the MS5000 with best signal to noise ratio for standard and research applications. Applications reaching from biochemistry, medical application throughout chemical characterisation.
Catechol estrogens are genotoxic, indirectly through redox cycling mechanisms leading to oxidative DNA damage and directly by formation of quinone–DNA adducts. Previously, we demonstrated that Cu2/ can oxidize estradiol (E2) catechols, establishing a copper redox cycle leading to the formation of DNA strand breaks.
