电感耦合等离子体质谱检测牡蛎中17种无机元素的含量
目的建立电感耦合等离子体质谱法(inductively coupled plasma mass spectrometry, ICP-MS)同时测定牡蛎中 17 种无机元素的分析方法。方法样品经微波消解后, 选用Rh为内标元素校正基体效应, 用ICP-MS进行分析。结果所测17种元素的相关系数均不小于 0.9990, 加标回收率在82.8%～111.0%之间, 相对标准偏差(relative standard deviation, RSD)在1.0%～7.1%之间。结论该方法快捷准确, 可用于牡蛎多种无机元素同时检测。
ObjectiveTo establish a method for the simultaneous determination of 17 inorganic elements in oysters by inductively coupled plasma mass spectrometry (ICP-MS). MethodsAfter microwave digestion, Rh was selected as the internal standard element to correct matrix effect, and ICP-MS was used for analysis. ResultsThe correlation coefficients of the 17 elements were not less than 0.9990. The recoveries were 82.8%?111.0%, and the relative standard deviations (RSDs) were 1.0%?7.1%. ConclusionThis method can be used to evaluate the mineral elements and safety of oyster due to its properties of rapid and accurate.
