Flow Systems with Electrochemical Sensors as Detectors

The evaluation of the performance of electrochemical flow-through sensors in unsegmented continuous flow systems dates back as far as 1970, when Pungor’s group was the first to report on the use of graphite electrodes for the voltammetric detection of samples injected into continuously flowing streams [1]. In 1975 Ruzicka and Hansen [2] coined the term flow injection analysis (FIA), when ana­ lytical chemists became aware of the scope and potential of this technique.
