摘要
为保证原子吸收分光光度计测量数据的可信度和准确度,在两次校准期间,使用铜、镉两种标准物质对其检出限、测量重复性、线性误差进行核查,结果发现各项指标都符合规程要求,核查结论为合格。
In order to ensure the reliability and accuracy of the measured data of atomic absorption spectrophotometer,two kinds of standard material Cu and Cd were used to check limit of detection,measurement repeatability,linear error.It was found that all indicators met the requirements of the regulations,and the verification conclusion was qualified.
