摘　　要：建立了电感耦合等离子体-质谱法快速、准确测定进口葡萄酒中18种元素的方法。根据葡萄酒的性质,探讨了测定介质的选择,样品的稀释倍数,使用内标校正技术来消除干扰。运用ICP-MS测定进口葡萄酒中18种元素时,各元素的线性范围为1.0-500.0μg/L,相关系数均达0.999以上,各元素的测定低限为0.015-0.357μg/L,相对标准偏差为1.70-4.83%,加标回收率为82.0-106.0%等,结果较为满意。To establish the rapid and accurate determination of 18 metals in wine by ICP-MAS. According to the nature of the wine, this paper discussed the medium of the methods and how to dilution the sample. Internal standard elements was used to compensate matrix effect. The linear range of 18 metals was 1.0-500.0μg/L, r >0.999,MDL was 0.015-0.357μg/L, the relative standard deviation is in the range of 1.70-4.83%, and the recovery is in the range of 82.0-106.0%.
