Total nitrogen determination in water impact on accuracy analysis affect its the main factors, including before processing, the work curve drawing, the determination of the reproducibility of the sample and the preparation of standard substances. Operating personnd can be improved by taking business technical level, repeatedly drawing work the curve, appropriate increase in the number of repetitions of samples and other methods improve the measurement accuracy.
