Certified values of iodine in CRMs of food matrices in mg/kg units. The uncertainties are expanded uncertainties at approximately 95% confidence.

A comparison of the expanded uncertainty for certified values of iodine in food matrix CRMs. The CRMS were found by searching The European Virtual Institute for...食品基质有证参考物质（Certified Reference Materials, CRMs）中碘认定值的扩展不确定度对比分析。本次研究涉及的有证参考物质均通过检索欧洲虚拟研究所（The European Virtual Institute）……获取。
