	<span style=\"font-size:14px;\">评定电感耦合等离子质谱法测定草鱼中20种元素的不确定度。根据实验过程中变量因素并结合JJF 1059.1-2012《测量不确定度评定与表示》的有关规定，分析影响各元素结果的不确定度因素，结合分析样品称量、样品消解、溶液制备、工作曲线拟合、测量重复性等因素对不确定度分量的影响建立模型，并对不确定度进行了评估。各元素的相对扩展不确定度在0.011~0.213 mg/kg之间，满足正常的工作需求。不确定度主要来源于标准曲线拟合和样品重复性测定两方面。</span><span style=\"font-size:14px;\"><br />
To evaluate the uncertainty of 20
elements in grass carp by inductively coupled plasma mass spectrometry (ICP-MS).
According to the actual situation and JJF 1059.1-2012 measurement uncertainty
evaluation and representation, the uncertainty factors affecting the results of
each element were analyzed. The model was established and the uncertainty was
evaluated by combining the influence of sample weighing, sample digestion,
solution preparation, working curve fitting, measurement repeatability and
other factors. The relative expanded uncertainty of each element is in the
range of 0.011~0.213 mg/kg, which meets the requirements of normal work. The
uncertainty mainly comes from the standard curve fitting and sample
repeatability measurement.</span>
