在国际贸易日益活跃的今天,食品安全问题越来越引起世界公众的关注,科学的、客观的检测结果将会越来越得到法律和社会的认可,特别是检测限量越来越痕量化、超痕量化的情况下,如何按照国际通行计量溯源的规则保证食品检测质量的一致性和真实性是食品安全检测领域备受关注和需要解决的问题。鉴于此,本刊特别策划了“食品检测实验室质量控制与标准物质”专题,由中国计量科学研究院张庆合教授担任专题主编,围绕化学检验计量溯源和实验室质量控制(人员、仪器和设备、环境、测量方法)、实验室 With the increasingly active international trade, the issue of food safety has drawn more and more public concern worldwide. The scientific and objective test results will be more and more recognized by the law and the society. In particular, the detection limit is getting more and more traceable. In the case of trace quantification, how to ensure the consistency and authenticity of the quality of food testing in accordance with internationally accepted rules for the measurement and traceability is a concern and problem to be solved in the field of food safety testing. In view of this, we specially planned the topic of “Quality Control and Standards for Food Testing Laboratories” and was co-edited by Professor Zhang Qinghe from China Institute of Metrology. Focusing on chemical traceability and laboratory quality control (personnel, instrumentation and Equipment, environment, measurement methods), laboratory
