按《检测和校准实验室认可准则》(CNAL/AC01:2003)[1]要求,从测量结果和不确定度评价的数学模型中采集气样部分Vo和采气后滤膜消化液待测物质量m两个方面,分析测定工作场所空气中砷的全部实验过程,确定不确定度,合理判定测量结果,为检测机构实施实验室质量体系管理提供参考。1材料与方法1.1依据国家职业卫生标准《工作场所空气中砷及其化合物的测定》GBZ/T160.31-2004中的第一法
According to the requirements of “Accreditation Criteria for Testing and Calibration Laboratory” (CNAL / AC01: 2003) [1], the gas sample Vo and the post-capture membrane digestion fluid sample are collected from the mathematical model of measurement and uncertainty evaluation Quality m two aspects, analysis and determination of workplace arsenic in the air all the experimental process to determine the uncertainty, a reasonable determination of the measurement results for the testing agencies to implement the laboratory quality management system provides a reference. 1 Materials and Methods 1.1 According to the national occupational health standards “Determination of arsenic and its compounds in the workplace air” GBZ / T160.31-2004 in the first method
