Abstract
Disclosed is a sensing system and method utilizing a sensor cartridge (10) for making analytical measurements regarding one or more samples (50) of interest, the cartridge (10) comprising an opaque housing (12) having an opening (32), the opening (32) allowing access to one or more electrically conductive contacts (34) and one or more fluidic connectors (36) disposed within the housing (12) and mechanically aligned to the electrically conductive contacts (34), a flow cell (56) having one or more channels connected to the one or more fluidic connectors (36), and a fixed optic sensor (68, 58, 72, 74) disposed within said housing (12) and aligned to a sensing surface on the flow cell. The fixed optic sensor may be, for example, a surface plasmon resonance sensor, a critical angle sensor, or a fluorescence-based sensor. In one embodiment of the present invention, the one or more electrically conductive contacts (32) comprise card-edge contacts (34). In an alternative embodiment of the present invention, the one or more electrically conductive contacts comprise conductive pins (124) intended to be inserted into a socket (128) of a reporter unit (130). Because the optic sensor is pre-ali…
