PIEZOELECTRIC SENSOR ARRANGEMENT

摘要

A piezoelectric sensor arrangement for analysis of fluid samples, which includes a signal source, a measuring device and a docking system, which comprises a first part (8) provided with means (9) for receiving a sensor element (10) that exposes a piezoelectric quartz crystal (32) and a second part (11, 12) comprising fluid channels (13) for the sample and a flow cell element (14), which preferably is removable and which comprises a recess (45), and inlet and outlet fluid channels (46) for leading a fluid through the recess. Said first and second parts are movable in relation to each other between a closed position and an open position and are arranged such that in the closed position the recess (45) of the flow cell element (14) is sealingly covered by the piezoelectric quartz crystal (32) so that a flow cell is formed by said flow cell element and said quartz crystal.
