Quality control and quality assurance in the chemical laboratory of the municipal sewage plant

质量控制与质量保证是水质化验室工作的重要组成部分。在水质化验室的工作中,采用测定程序空白值、加标回收、平行测定等质量控制手段,从不同方面来验证方法的准确度和精密度。质量保证体系是化验室内部实施质量管理的法规,覆盖了样品采集、检测过程、仪器设备、人员素质等全部质量控制要素,从而保证化验室所获得数据的可靠性。

Quality control and quality assurance are the important parts in the process of testing water quality in the chemical laboratory. In testing the water quality,we verify the accuracy and the precision of the methods in various aspects such as blank value assay, recovery rate experiment and parallel determination experiment. The quality guarantee system follows the regulations about quality management that assure the reliability of the data in the chemical laboratory, which covers all the element factors about quality control such as example collecting, the detection procedure, the detection equipment, and the qualification of the test controller.
