Abstract
Electrochemically generated chromophores are measured by passing a beam of electromagnetic radiation parallel and close to the surface of the electrode at which they are being generated, and collecting the diffracted radiation. The response is so rapid (.about.0.025 sec.) that modulation is practicable and the path length, which is set by the thickness of the electrode, is much greater than in optically transparent electrodes, thus rendering the method very sensitive to weak chromophores or low concentrations.
