摘　　要：通过对实验室流动分析设备的改进,进行船载流动分析的定制,同时对船载流动分析绘制总氮的标准曲线,测定仪器的空白值、检出限和测定下线,以及仪器的A类不确定度进行分析,对比船载流动分析在实际水体监测和采样到实验室分析结果。结果表明,在保证测定结果准确度和精密度的前提下,船载流动分析系统具有较好的测试灵敏度。Through the improvement of laboratory flow analysis equipment,the customization of shipboard flow analysis was carried out,and the standard curve of total nitrogen was drawn for shipboard flow analysis.The blank value,detection limit and downline of the instrument were determined.And the A type uncertainty was measured in actual water monitoring and sampling to laboratory analysis.The results showed that the shipborne flow analysis system had better test sensitivity under the premise of ensuring the accuracy and precision of the measurement results.
