摘要
液相色谱-原子荧光光谱联用仪已经成为As、Hg、Se、Sb等元素形态分析的重要工具,广泛应用于食品安全、农产品检测、环境科学等领域。本文以《液相色谱-原子荧光联用仪检定规程》(JJG 1151—2018)和《测量不确定度评定与表示》(JJF 1059.1—2012)为依据,详细讨论了液相色谱-原子荧光联用仪对3种形态砷最小检测量的测量不确定度评定过程及方法,对主要分量进行了不确定度分析和评定。
Liquid chromatograph tandem atomic fluorescence spectrometer has become an important tool for the morphological analysis of As, Hg, Se, Sb and other elements. widely used in food safety, agricultural products testing,environmental science and other fields. In this paper, based on JJF 1059.1—2012 and JJG 1151—2018, the uncertainty evaluation process and method of liquid chromatograph-atomic fluorescence spectrometer for the minimum detection amount of three forms arsenic were discussed in detail. The uncertainty of the main components is analyzed and evaluated.
