Spectrophotometric flow-injection techniques for the multicomponent monitoring of process streams

An overview of simultaneous determinations in flow-injection analysis (FIA) is presented and the advantages of photodiode array detection are discussed. The application of multivariate calibration procedures to nonselective data is outlined and examples of its use in FIA are reviewed. The role of flow-injection techniques in process analysis and the potential of FIA-photodiode array-multivariate calibration systems for on-line multideterminations are also considered.
