大米中镉的测定能力验证

Verification on Capability for Determination of Cadmium in Rice

为了解中国实验室在食品安全等重点领域的检测能力,加强相关实验室能力建设,中国国家认证认可监督管理委员会(CNCA)近年来组织开展了包括大米中镉的测定能力验证等一系列检测能力验证活动。通过对大米中镉的测定能力验证的研究,获得了来自23个省、自治区和直辖市的54个实验室能力验证活动的统计分析和技术分析结果,检测结果(含补测)满意的实验室占88.9%。

In order to find out the determination capability of Chinese laboratories in food security and other important fields and enhance relevant laboratory proficiencies,China National Certification and Accreditation Committee(CNCA) has developed a series of determination capability testing programs,including testing on determination capability of cadmium in rice.The results of statistical and technical analysis on capability testing of 54 laboratories from 23 provinces,regions and cities were obtained through study on capability for determination of cadmium in rice.Where,laboratories which obtained qualified results(including later determination) took up 88.9 % of the participating labs.
