Abstract | Flow injection analysis (FIA) systems with low power consumption and personal-computer control were developed by using solenoid pumps and an LED detector. Both programs for controlling the system and acquiring measurement data were written using LabVIEW. The FIA system was applied to the determination of nitrite ion in river-water samples based on diazotization and coupling reactions. Linear calibration graphs were obtained with the combination of pump(s) and photometric detector in the concentration range of nitrite ion at 0.5∼3.0 × 10−6 M. Nitrate and nitrite ions were also determined simultaneously by the system by using a Cd/Cu reduction column and a by-pass flow. Determination of ammonia in river-water samples was also realized by the system with a modified indophenol reaction.
