Abstract
A device for centering an elongated sample tube (), filled with a measuring substance, relative to a vertical axis of a nuclear magnetic resonance (NMR) receiver coil system () which is rigidly mounted in a support device is characterized in that at least two centering means are provided which are mutually separated in an axial direction of the receiver coil axis and act exclusively in a radial direction on the sample tube (), one of which is disposed in the upper region () and the other in the lower region (') of the NMR receiver coil system () and with at least one positioning means acting on the sample tube () in an exclusively axial direction which may be located either below () or above () the NMR receiver coil system, wherein the exclusively radially acting centering means (′) are components of the NMR receiver coil system (). The centering accuracy can be increased compared to known devices to obtain optimum results even for sample tubes in the form of measuring capillaries which pose the highest requirements with respect to centering accuracy.
