PIEZOELECTRIC RESONATOR |
摘要 |
<p>A piezoelectric resonator for use in a sensor arrangement for detecting or measuring an analyte in a medium, comprises a quartz crystal plate, having a first crystal surface and a second crystal surface. The first crystal surface is provided with a first electrode, which has a surface area of less than 15 mm<2 >and the second crystal surface is provided with a second electrode. The first electrode may have a rectangular surface shape. A flow cell for use in an apparatus for detecting or measuring an analyte in a medium, comprises walls that form a sensing chamber together with the resonator, and inlet and outlet openings for leading a fluid through the sensing chamber. A part of the resonator constitutes one of the walls of the sensing chamber and is arranged such that the first electrode is situated inside the sensing chamber.</p> |
