Abstract
An automated chemiluminescence analyzer. A multiport selection valve has a common aspiration port for carrier solvent, sample, and reagent. A bi-directional pump is connected to the selection valve. A chemiluminescence cell is positioned between the selection valve and a T-block. One end of the cell is connected to the common port of the selection valve, and the other end is connected to the T-block. The T-block has a port connected to the pump, another port which communicates with the detector, and a third port connected to the other end of the cell. This unique arrangement enables the chemiluminescence cell to function as a chemical reactor, thus eliminating any delay between initiation and detection of emitted radiation, so that very rapid reactions can be viewed and high sensitivity attained.
