A quartz crystal sensor cell comprising a housing (20, 21, 41, 410, 411) having a well (22, 42) to receive a sample carrier fluid, an aperture (23) in the base of the well (22, 42) to receive a quartz crystal sensor (25, 40), and a sensor (25, 40) located in the base of the well (22) so that a peripheral surface of the sensor (25, 40) lies against a peripheral surface of the aperture (23), and the sensor (25, 40) is secured to the base of the well (22, 42) by a layer of adhesive (26) between the respective peripheral surfaces. |
