A sensor arrangement is described in which a semi-conductor component, such as an ion-selective field-effect transistor (ISFET) (5) is secured to a ducting component (1) containing ducts (2,3) to carry fluid towards and away from a sensitive region of the ISFET (5). The two components (1,4) are secured together by means of a gasket (6) formed of porous material and apertured where adhesion of the components to one another is not required. The gasket (6) is inserted between the components (1,4) and adhesive applied to an exposed portion (7), such as a tab, of the gasket. The adhesive is distributed by capillary action to all parts of the gasket and secures the components together without affecting those areas of the components juxtaposed with the apertured region or regions of the gasket. |
