Abstract
A flow cell for chemiluminescence analysis. The flow cell has a flat, thin, opaque plate, with a groove machined into one side of the plate. An inlet port at the center, and an outlet port at the outside end of the groove pass through the plate, which is sandwiched between a flat sapphire window and a cell cap of a housing. The groove side faces the sapphire window, forming a flow channel with one wall being the sapphire window. A light detector is inserted into the housing until it butts up against that part of the housing holding the sapphire window, placing it very close to the generated light. The other side of the plate mates with inlet and outlet ports of the housing cap.
