Researchers used flow injection analysis (FIA) and high performance liquid chromatography (HPLC) to monitor the exhaustion percentage and hydrolysis of reactive dyes. The FIA system included a syringe pump, low pressure sampling valve, mixing chamber, and diode array detector. HPLC equipment included a Waters 600E pump, Waters 991M photodiode array detector, Waters Bus LAC/E interface, and Waters Millennium Chromatography Manager software. Partial least squares predicted dye concentrations. Integration of the FIA and HPLC systems provided pseudo-real time data on hydrolysis and exhaustion levels. Although the chromatographic data were useful, the cost of technique was high. 22 refs.
