Abstract
The valve arrangement comprises a predetermined number of individual valve functionalities, arranged in a manner parallel to each other. A fixed connector plate (3) has a number of sample funnel tubes (6) and output connections (8) for forward transfer of the samples arranged offset from the above. A valve plate (14) with the same number of sample loops (24) for accommodating precisely measured sample amounts may be displaced linearly with respect to the connector plate. In a first position the sample loops are connected to the sample funnel tubes and in a second position with the output connections.
