Ion Chromatography and Flow Injection Analysis systems were integrated by a switching valve. Then, sampling kit was designed by disposable syringe, 0.45um syringe filter, and 2mL plastic vial. 13 water samples were collected from oxidation pond and natural stream in a University campus. Four analytical modes were applied for standard solutions and the environmental samples. The detection limit (S/N =3) in µM/L were as follows, SO42- (0.31), Cl- (0.50), NO3- (0.89), Na+ (0.52), NH4+ (0.94), K+ (1.24), Mg2+ (0.76), Ca2+ (1.75), NO2- (0.02), and PO43- (0.12), and its EC was 0.03µS/cm. Our analytical approach was simple, rapid,low-cost, and multi-parameter that was satisfactory to assess the water samples. Due to the sampling, transportation, storage processes are drastically improved, our approach has potential to contribute to strategic environmental assessment.
