摘要：ICP-MS作为痕量分析的主要仪器，检测所需试剂少，检验时间快，检出限低，测定结果准确可靠。该文以保健食品为例，来进行ICP-MS 法测定总砷的方法验证。样品经微波消解处理后，依据GB 5009.11-2014 第一法电感耦合等离子体质谱法（ICP-MS）来进行检测。同时实验测定了方法的检出限、精密度及准确度，均能满足标准要求和实验室的要求。

Abstract: As the main instrument for trace analysis，ICP-MS has few reagents，fast test time，low detection limit，andaccurate and reliable results. This paper takes health food as an example to verify the ICP-MS method for the determinationof total arsenic. Samples were treated by microwave digestion and detected by GB 5009.11-2014 first inductively coupledplasma mass spectrometry （ICP-MS）. At the same time，the detection limit，precision and accuracy of the method weredetermined，which can meet the standard requirements and laboratory requirements.
