Abstract

The invention relates to a sample cell (1) for performing DNP-NMR measurements, for interchangeable use in an EPR microwave resonator (28), with the sample cell (1) comprising - a flat sample cavity (6) for holding a liquid (23) sample to be measured, wherein the flat sample cavity (6) extends with a maximum length L and a maximum width W in a sample cavity plane (19), and extends with a maximum height H perpendicular to the sample cavity plane (19), with H ≤ 1/15*L and H ≤ 1/15*W, and - an NMR coil (4) wound around the flat sample cavity (6) for generating an RF magnetic field B<2>, wherein a coil axis (4a) of the NMR coil (4) about which the NMR coil (4) is wound is oriented perpendicular to the sample cavity plane (19). The invention provides a sample cell which is easy to handle and improves the quality and the reproducibility of DNP-NMR measurements.
