Nmr - spectrometer with ergonomically favorable sample changer

摘要

A nmr - spectrometer (1 '') comprising a magnet arrangement (2) with a vertically oriented receiving opening for receiving a along a sample extended nmr - sample with a measuring volume (3), in which the elongate nmr - sample during the implementation of an nmr - measurement in a measuring position with a vertically oriented sample is positioned, as well as with a sample changer (4'') with at least one cylindrical sample holder (7 '', 7 ") for receiving the nmr - sample to a loading position (5) and for the transfer of the nmr - sample in the measuring volume at a transfer position (6), is characterized in that the cylinder axis of the cylindrical sample holder of the weighing object changer to the loading position by an angle of inclination α of between 30 and 60 degrees with respect to the vertical is inclined, whereas it runs vertically to the transfer position, and in that a positioning device is provided, which - the nmr sample at the transfer position, or after passing through them into the measuring position in the measuring volume with a vertically oriented sample transferred - of the nmr sample. In this way, an ergonomically more favorable sample delivery on the nmr - spectrometer enables.
