Using the CFA1000 continuous flow analysis system, the total nitrogen in water was determined through the calibration curve.Class A uncertainty of the instrument was evaluated by the determination of the blank value, detection limit and minimum quantitative detection limit.CFA1000, SKALAR, and SAN++continuous flow analysis systems were compared for their determi-nation methods as well as the analysis results using the national standard method.The results showed that CFA1000 continuous flow analysis system had the highest sensitivity for detection among the three systems.
