An NMR spectrometer () with a magnet system (), which has a bore () through the magnet center () for inserting a measuring sample () in a transport container (), and with a transport device for pneumatic transport of the sample through a transport channel () into and out of the magnet system. The transport device includes a mechanical interface () with a mounted exchange system () which has parking receptacles () temporarily storing the transport containers. In a transport position, the parking receptacle is inserted into the transport channel, to be loaded with a transport container, removed from the transport channel for temporarily storing the transport container, and reinserted into the transport channel for further transport of the transport container. In the transport position, the parking receptacle forms a part of the transport channel, which permits a faster automated change of the measuring samples in short measurement cycle times.

NMR spectrometer with quick-change system for samples

Transport apparatus pneumatically conveying NMR test samples () from or to an NMR spectrometer () through a tubular transport channel () includes a device () generating positive pressure in the end of the transport channel that is remote from the spectrometer. The transport channel has a tube system which has a gas-tight outer tube () having an outer diameter Dand an inner diameter dand an inner tube (), arranged coaxially with respect to the outer tube, having an outer diameter D&#x3c;dand an inner diameter d. The inner diameter dof the inner tube is greater than or equal to the outer diameter Dof the test samples, and the inner tube includes mutually spaced cross-holes () designed as through-holes. This provides accurate current position determinations for the sample in the transport channel, and reduced risk of damaging the sample during transport.

Transport apparatus for temperature-controlled NMR test samples having a double tube system

A transport device for transporting an NMR sample to a probe head (), having a shuttle () and a locking apparatus () for the rotor (), which, when attaching the shuttle to the probe head, releases the rotor, and having a detecting apparatus for detecting the rotor in the shuttle. The probe head has a positioning apparatus (), which holds the probe head in a defined measuring position relative to the shuttle. The detecting apparatus includes a sensor line, which transmits a signal dependent on the position of the probe head to the shuttle's end. A first portion () of the sensor line is mounted inside the shuttle and extends from the rotor in a transport state to the end of the shuttle. A second portion () of the sensor line is mounted inside the probe head and, in the measuring position, is directly adjacent to the first portion.
