化学分析实验室标准物质的使用中应注意的几个问题

Discussion n Some Problems That Should Be Paid Attention To In The Use Of Reference Materials In Chemical Analysis Laboratory

随着科技的进步与发展,人们的日常生产生活与化学分析监测的关系越来越紧密。标准物质是化学分析监测实验室一种重要的试剂,对保证测量的准确性具有十分重要的意义。本文就标准物质的分级,标准物质的用途,标准物质的储存方法以及标准物质在使用过程中的浓度选择、级别选择等方面展开论述,供各化学分析实验室参考。

With the progress and development of science and technology,the relationship between people’s daily life and chemical analysis has become more and more close.Reference material is an important reagent in chemical analysis and monitoring laboratory,it is very important to ensure the accuracy of measurement.In this paper we discussed the classification of reference materials,the use of reference materials,the storage method of reference materials.concentration selection and grade selection of reference materials in use were also discussed.We hope this article will be helpful to the laboratory works.
