ICP-MS分析国际比对样品中无机元素含量

Determination of Inorganic-element Contents in the International Proficiency Test Samples by Inductively Coupled Plasma-Mass Spectrometry

本试验应用电感耦合等离子体质谱法（ICP—MS）参加了英国食品分析水平评估计划（FAPAS）组织的国际测试活动，即FAPAS0758和FAPAS0761样品中的无机元素分析。反馈的统计结果显示两份样品共7个元素含量的Z值在0．0～1．3之间，结果均令人满意。

The report participated in two international profiency testings conducted by FAPAS, i.e. FAPAS0758 and FAPAS0761. The feedback statistics showed that Z-score of the seven elements in two samples were all between 0.0 and 1.3. The result was satisfied.
