原子吸收光谱仪检出限测量不确定度的评定

测量不确定度是表征合理的赋予被测量之值的分散性,与测量结果相联系的参数,本文为依据JJG 694-2009《原子吸收分光光度计检定规程》和JJF 1059-1999《测量不确定度评定与表示》,对原子吸收光谱仪的检出限进行了校准并对其不确定度进行了评定。

The measurement uncertainty is reasonable characterization the value of the measured dispersion, parameter associ-ated with the measurement results, this paper is based on ＂JJG 694-2009 atomic absorption spectrophotometer verification regula-tion of JJF＂ and 1059-1999 ＂evaluation and expression of uncertainty in measurement＂, the detection limit of atomic absorption spectrometer was calibrated and the uncertainty was evaluated.
