Abstract:
A nuclear magnetic resonance spectrometer comprising:a) a magnet for applying a magnetic field to a plurality of nuclear magnetic resonance samples; b) a nuclear magnetic resonance probe positioned in a bore of the magnet, for performing nuclear magnetic resonance measurements on the samples; and c) an axial multi-sample conveyer coupled to the probe, for transferring a plurality of sample containers containing the samples into the probe, the conveyer comprising: a plurality of input apertures for receiving the sample containers, a plurality of output apertures positioned opposite the input apertures and transversely aligned with the plurality of input apertures, for sequentially transferring the sample containers to the probe, an axially-rotatable auger positioned between the input apertures and the output apertures, for axially constraining a motion of the sample containers between the input apertures and output apertures, and a plurality of axial sample guides positioned facing the auger between the input apertures and the output apertures and transversely aligned with the input apertures and the output apertures, for transversely constraining the motion of the sample containers.
