探讨了微波消解结合电感耦合等离子体质谱（ICP-MS）标准（STD）及碰撞池（KED）两种模式测定亚麻籽中微量元素铜、铁、锌、锰方法的有效性。分析比较了两种模式的测定效果，在此基础上选择各元素的有效测定模式，并对四种微量元素的分析结果进行不确定度评价。根据不确定度评判标准JJFl059-1999《测量不确定度评定与表示》中的规定，逐一分析了影响不确定度的主要因素，并对各不确定度进行了计算。结果表明ICP-MS用于测定亚麻籽中微量元素结果令人满意，同时为ICP-MS测定这四种元素的不确定度评价提供了一定的参考价值。

Copper ,iron ,zinc and manganese in flaxseed were determined by inductively coupled plasma mass spectrometry (ICP-MS) .After digestion by microwave-assisted ,Cu ,Fe ,Zn and Mn were analyzed by using Standard and KED modes .In the pres-ent study ,testing effectiveness of the two modes was compared .On this base ,valid determination mode was selected for each of the elements and uncertainty evaluations of the four microelements were explored .According to JJFl059-1999 (Evaluation and Expression of Uncertainty in Measurement ) ,the main influence factors were analyzed one by one .Each of the uncertainties was calculated separately .It was showed that the results of Cu ,Fe ,Zn and Mn in flaxseed determined by ICP-MS method were sat-isfactory .At the same time ,the results obtained in this work were considered to be valuable as a reference for the evaluation of uncertainty in measurement of Fe ,Cu ,Zn and Mn with ICP-MS .
