Abstract
Sensor cartridges include a fluid constituent-selective sensor membrane in direct sealing contact with a face of a flow-through sample cell in surrounding relationship to a sensor port. The sensor membrane has sufficiently large surface area so as to entirely cover the sensor port and establish an annular region in surrounding relationship thereto. It is this annular region which is in direct contact with a corresponding region of the sample cell face so as to provide self-sealing capabilities. The sensor cartridge most preferably includes a flow-through sample cell having a zig-zag or serpentine flow channel so as to provide a series of sensor ports on both of the opposed cell faces. The faces of the sample cell are most preferably provided with recessed regions which define a series of land surfaces each of which surrounds a respective one of the sensor ports. A pair of sensor arrays having a corresponding series of sensors are thus juxtaposed with a respective land surface of the sample cell face so as to sandwich the sample cell therebetween. A two-part 'clamshell' housing houses the sensor arrays and the sample cell sandwiched therebetween.
