标准物质是具有一种或多种性能、足够均匀和很好的确定特性,用以校准测量仪器、评价测量方法或给材料赋值的一种材料或物质[1],所以可以作为参照物或质控样对实验室的检测数据的准确性和可靠性进行核查,从而可以帮助实验室查找在人、机、料、法、环等检测因素方面的偏差,以便实验室有针对性的采取纠正措施和预防措施,对于提高数据的准确性、可靠性是很有效的质量控制手段。一般来说,标准物质密闭在容器中保存时,其稳
A standard substance is a material or substance that has one or more properties that are uniform and well defined, used to calibrate a measuring instrument, to evaluate a method of measurement, or to assign a value to a material [1], so it can be used as a reference or substance Control samples to verify the accuracy and reliability of the laboratory test data, which can help the laboratory to find people, machines, materials, France, Central and other detection factors deviation, so that laboratories to take corrective measures And precautions, reliability is a very effective quality control measure to improve the accuracy of the data. In general, the standard material is hermetically sealed when stored in a container
