摘　　要：将电感耦合等离子体-质谱(ICP-MS)技术应用于番茄酱中的无机元素分析,实现一次制样,同时测定番茄酱中13种食品安全相关元素含量。本文给出铅、镉、铬、汞、砷、锡、锌、铜、铁、锰、铝、镍、硒等13种元素的方法检出限为0.61～125.7μg/L,回收率为83.8%～112.5%,RSD值为0.3%～5.0%。该方法分析速度快、操作简单,方法检出限、精密度和线性范围均能满足出口番茄制品食品安全检测的相关要求。The method of inductively coupled plasma-mass spectrum（ICP-MS） was firstly applied for the determination of 13 trace elements in tomato paste. It comes true, once preparation of sample, the 13 elements in tomato paste could be tested by ICP-MS synchronously. The limits of detection for method are 0.61-125.7μg/L. the recoveries are 83.8%-112.5%, and the RSD are 0.3%-5.0%. The method was simple, fast and the limits of detection, precision, linear range of method can suffice the requirements for determination of food safety.
