FLOW-INJECTION TITRATION - LINEAR OR LOGARITHMIC

A simple and rapid Continuous Flow Injection Titration method utilizing a pretitration step was developed to automate the assay of high sulfuric acid concentrations over a narrow range in an oil refinery stream. A Coulometric Flow Injection Titration method was developed to perform Karl Fisher titration. Multiple functions of the mixing chamber in these FIA titrations such as for pretitration dilution, and reduction of viscosity are discussed. The cell also serves as the detector. Appropriate combining of these functions allows FIA titrations to become a powerful tool in automating routine assays.
