浅谈标准物质的期间核查

Discussion on Intermediate Checks of Standard Substance

标准物质是实验室方法开发、确认、质量控制的重要基础,只有保证标准物质的准确性和有效性才能得到可靠的实验数据,而标准物质在储存和使用过程中,其量值有可能发生改变,这种变化会对实验结果产生直接影响.标准物质的期间核查是质量保证工作计划的重要组成之一.本文介绍了标准物质期间核查的意义并对标准物质期间核查的计划、间隔、方法、结果及评价等方面进行了简单探讨.

Standard substance is very important for the development, confirmation and quality control of laboratory methods. Reliable experimental data can be obtained by ensuring the accuracy and validity of standard materials. While the amount of standard substance may change during the process of storage and usage, and the change will have a direct impact on the experimental results. Thus, the significance of the inspection during the period of standard substance was introduced, and the plan, interval, method, result and evaluation of the inspection during the period of standard substance were discussed briefly.
