Abstract: A flow-through sample container, or flow cell, according to the present invention resides with the channel of magnetic resonance probe without being fixed thereto. The flow cell is removable from the spectrometer while leaving the probe in place, allowing easy cleaning of the probe channel and replacement of the flow cell. An insertion tool that houses the flow cell may be used to safely introduce it to the probe. Input and output capillaries serve as fluid pathways for fluid samples entering and leaving the flow cell, respectively. These capillaries may be connected to the flow cell with a manually operable connector, allowing easy disconnection of the flow cell from the input and output conduit. The capillaries enter through different ends of the spectrometer bore, so that the fluid samples flow enter one end of the spectrometer and exit through the other.

Abstract: An actuating drive for controllable adjustment of a plurality of actuators in a nuclear resonance spectrometer is characterized in that the actuating drive has a drive train with a drive shaft (9) that can be driven by an electric drive motor (3) and with a plurality of drive train outputs, for coupling to the actuators, each of which can be individually coupled to the drive shaft by means of a changeover device. This enables the actuators to be adjusted automatically.

Abstract: In a temperature-control device for samples, in particular for NMR spectroscopy, comprising a vessel (20) provided with an opening (19) for receiving a measuring sample (1), an inlet opening (10) for introduction of the fluid, an outlet opening (15) for the outflow of the fluid and a flow channel (18) through which at least a partial flow of the fluid is guided past the sample (1), as direct fluid flow, from the bottom to the top, there is provided at least one by-pass channel (17) which is arranged in such a way that an additional partial fluid flow can be guided past the upper area of the said sample (1) in the form of a by-pass fluid flow (7). This enables also the upper area of the sample (1) to be temperature-controlled in an efficient way so as to minimize the temperature gradient in the sample (1).
