采测分离过程中的质量控制和质量保证

Quality control and quality assurance in the separation process

质量控制和质量保证是地表水环境监测中控制误差,保证数据科学真实的重要手段。本文以氨氮、总氮和总磷为分析指标,对地表水监测采测分离全过程质量控制和保证措施进行了研究,对质量控制和保证措施进行了验证。结果表明,全程序空白和实验室空白都在可控范围内,说明该控制措施可保证监测数据的精密度和准确度。

Quality control and assurance are the important means of controlling errors in surface water environment monitoring and ensuring the authenticity of data science. The quality control and assurance measures for the whole process of surface water monitoring and separation were studied. Ammonia nitrogen, total nitrogen and total phosphorus were taken as the analysis indicators to verify quality control and assurance measures. The results show that the control measures can guarantee the precision and accuracy of the monitoring data, and the entire program blank and lab blank are within the controllable range.
