从NIST Ca标准溶液证书的演变规律揭示标准溶液的使用原则

Using principle of standard solution from the evolution rule of NIST Ca standard solution certificate

重点揭示了标准溶液的使用原则。通过对比近30年来NIST Ca标准溶液证书的演变,提出了标准溶液应用的注意事项,并对无机单元素标准溶液的标准值、有效期、定值方法、介质、包装材质及应用等6个方面的技术要素进行了系统地研究与分析。该研究提供了详实的技术信息,有助于实验人员正确地识读和学习证书信息,并合理应用无机单元素标准溶液。

The application principle of standard solution was revealed.By comparing the evolution of NIST Ca standard solution certificate in the past 30 years,the matters needing attention in the application of standard solution were put forward.The technical elements of standard value,validity period,method of setting value,medium,packaging material and application of the inorganic single element standard solution were systematically studied and analyzed.This study provides detailed technical information,it is helpful for the experimenters to correctly read and learn the certificate information,and to rationally apply the inorganic single element standard solution.
