【Abstract】 A sequential injection photometric analysis system with automated optimization function was developed. The system was composed of a syringe pump, a 10-port selection valve and a spectrophotometer flow through detector. Operating parameters for the instrument setup, data collection and processing were performed by a computer. A modified simplex method was used to perform system optimization. The optimization program was integrated into the controlling software of the system to perform automatic optimization. The optimum parameters for SIA determination of phosphate by the molybdenum blue method were obtained automatically by such a system within 4 hours.更多还原
