Abstract

Measuring the oxygen content in superoxygenated table waters and following the oxygen loss upon storage of such waters in open containers is presented as an experiment for NMR relaxometry in the student lab. The influence of dissolved paramagnetic oxygen molecules on the relaxation behaviour of the water protons is both of interest as a possible source of artifacts in NMR spectroscopy and as a possible contrast mechanism in biomedical applications of magnetic resonance imaging (MRI).
