Abstract: The extraction system according to the invention for extracting analytes from a sample comprises an extraction cell for receiving the sample, which has at least one first fluid connector for the supply or discharge of a fluid, and a clamping device for clamping the extraction cell, and a fluid connection device for establishing a fluid connection with the at least one first fluid connector of the extraction cell, wherein an extraction cell holder is provided for receiving the extraction cell, and the clamping device has a guiding and positioning arrangement for linearly inserting the extraction cell holder, together with the extraction cell, in order to position the extraction cell in an insertion position.

Abstract: The clamping device according to the invention for clamping at least two processing devices for a sample preparation is made up essentially of at least three clamping blocks arranged in the axial direction, at least two of which are designed as movable clamping blocks, and a displacement mechanism for displacing the movable clamping blocks between an open position for inserting the processing devices, and a clamping position in which the at least two processing devices are clamped one on top of the other in the axial direction between two clamping blocks in each case. The displacement mechanism is designed for displacing the at least two movable clamping blocks in opposite directions.

Abstract: A clamping device for clamping a plurality of columns for sample preparation provides a plurality of clamping blocks and a displacement mechanism for displacing at least one clamping block relative to an opposing clamping block between an open position and a clamping position. At least three clamping blocks are retained in a row one behind the other on a guiding rail so that at least two columns can be clamped in an axial direction one behind the other between the clamping blocks. First and second slidingly displaceable clamping blocks of the least three clamping blocks are retained on the guiding rail and connected to the displacement mechanism by coupling means so that an actuation of the displacement mechanism from the clamping position into the open position brings about a displacement of all the slidingly displaceable clamping blocks and the columns are released.

Abstract: The transport and handling retention member comprises an adapter ring which has a central opening for receiving a tubular container for receiving samples, a gripping member for gripping the adapter ring, and a transfer head which can be moved between a rest position and an operating position, the transfer head in the operating position coming into operational contact with a tubular container which is received in the adapter ring.

Abstract: According to the invention, this object is achieved by a clamping device for clamping a plurality of columns for sample preparation which provides for a plurality of clamping blocks and a displacement mechanism for displacing at least one clamping block relative to an opposing clamping block between an open position and a clamping position. In this instance, in the open position, a column can be inserted between two opposing clamping blocks and, in the clamping position, the inserted column is clamped between the opposing clamping blocks in order to produce a fluid connection between the column and at least one of the opposing clamping blocks. In this instance, at least three clamping blocks are retained in a row one behind the other on a guiding rail so that at least two columns can be clamped in an axial direction one behind the other between the clamping blocks.
