<p>PROBLEM TO BE SOLVED: To provide an ergonomically more favorable sample feed on an NMR spectrometer.SOLUTION: An NMR spectrometer 1' includes: a magnet configuration 2 having a measurement volume 3 positioned at a measuring position of a sample axis on which an elongated NMR sample is vertically aligned during NMR measurement, and having a substantially vertically aligned elongated upper opening for receiving the elongated NMR sample extending along the sample axis, which is particularly located in a sample vial; and a sample changer 4' with at least one cylindrical sample holder 7', 7'' for receiving the NMR sample at a loading position 5 and for transferring the NMR sample into the measurement volume 3 at a transfer position 6. A cylinder axis of the cylindrical sample holder 7', 7'' of the sample changer 4' is inclined at the loading position 5 by an angle of inclinationαof between 30 and 60 degrees with respect to a vertical and extends vertically at the transfer position 6. The NMR spectrometer 1' also includes a positioning device, which transfers the NMR sample at or after the transfer position 6 into the measuring position in the measurement volume 3.</p> |
