摘要：目的：建立电感耦合等离子体质谱(ICP-MS)法测定保健食品原料深海鱼油中汞的含量并进行方法学研究。
方法：微波消解法制备供试品，电感耦合等离子体质谱全定量法采集数据。
结果：汞的标准曲线线性良好，相关系数(r)为0.9998，方法检出限为0.010μg/L。
结论：该方法灵敏度高，准确，适合于难消解的油脂类物质中汞的测定。

Chen Junhong
Abstract：Objective：To establish the determination method of mercury level in fish oil with ICP-MS.
Methods：Microwave assisted heating was applied to the digestion of samples， and Mercury in the sample were determined by inductively coupled plasma mass spectrometry.
Result： Standard curve of Hg showed a good linear relationship， with correlation coefficient of 0.9998， and the results were accurate and reliable. The detection limits reaches 0 ......
