Abstract
In the case of NMR spectrometers comprising a cryomagnet with vertical axis, the sample to be examined is introduced into the measuring area of the magnet by means of a sample carrier which is arranged in a guide tube passing axially through a central space of the craymagnet, and can be moved therein by means of a flow of compressed air. For changing the sample, one switches on the compressed air flow so that the sample carrier is raised to the upper end of the guide tube where the sample can be changed. With increasing sizes of the cryomagnets, the upper end of the guide tube is no longer accessible without an aid (ladder or platform). The invention therefore provides that a direction switch is arranged at the upper end of the guide tube and that an inclined tube extends from the said direction switch to an easily accessible point, for inserting and removing the sample carrier at its end. By guiding the flow of compressed air in a suitable manner and switching over the direction switches as required, the sample can then be moved from the measuring area to the end of the inclined tube, and vice versa, so that the difficulties described before are no longer encountered.
