对电感耦合等离子体质谱法测定的地下水中Ag元素不确定度的评定
Uncertainty evaluation for the determination of silver in groundwater samples by inductively coupled plasma-mass spectrometry
摘要
Abstract
The measurement uncertainty of the analytical results of Ag in groundwater samples by inductively coupled plasma-mass spectrotnetry (ICP-MS) was evaluated using continuous propagation model of uncertainty. The regression of double error was used in the course of standard curve fitting. The extended uncertainty of measurement results was obtained from the synthesis of uncertainties from each source. When the silver content of the actual samples is relatively low, the uncertainty generated in the course of standard curve fitting is comparatively large and even becomes the dominant factor.关键词
