Abstract
The invention concerns head for flowthrough NMR spectroscopy in which there is provided, in the interior of a vessel, a replaceable quartz cuvette which can be separated from the vessel, and eluent inflow and outflow tube, and a measurement coil, and which has end sections which seal with respect to the vessel. The parts constituting the vessel, namely a cylindrical glass casing, a cover, and a base, as well as the replaceable quartz cuvette, can be clamped together with a simple clamping device in such a way that the sample head according to the invention can also be used for high pressure, such as those which occur with SFC (supercritical fluid chromatography) NMR measurements.
