Abstract
A method and apparatus for conducting electrochemiluminescence (ECL) measurements which control the initial conditions relating to the surface state of a triggering working electrode by reproducibly creating and maintaining a favorable surface condition so as to enhance the precision and detection limit of the measurements. Assays are performed with ECL detection in a flow-through cell environment and the precision and detection limit are enhanced by alternating initialization and measurement steps.
