Sequential injection analysis using electrochemical detection: A review Review Article

Nowadays a laboratory should be able to analyse a large number of samples in an accurate, reproducible, quick and economic way. As sequential injection analysis (SIA) is becoming an important tool for the automation of chemical procedures, this paper presents an overview of the principles of operation and applications of this emergent methodology using electrochemical detection. SIA systems developed to date present good characteristics for routine use and the electroanalytical methods proposed show adequate figures of merit. In addition, the results obtained are in good agreement with those furnished by the application of the reference methods.
