适用范围

The accuracy of many analytical measurements is dependent upon the manner in which the standard solutions are prepared and stored, and the accuracy with which they are standardized. Combining the methods recommended for the preparation and handling of such solutions into one practice eliminates the necessity for covering such details in all of the methods wherein the solutions are used.

1.1 This practice covers procedures for the preparation, standardization, and storage of the standard volumetric solutions and reagent testing solutions commonly used in chemical analysis.

1.2 The information in this practice is arranged as follows:

怎样保证高质量超纯水稳定供应?

为了使实验室研究工业生产顺利进行,一些职能部门,例如ASTM(美国材料与试验协会)、CAP(美国病理学家协会)、ISO(国际标准化组织)以及VDI(德国工程师协会)等专门提出了水质量标准及规范。按照不同水纯化级别,可将水质分别定为4级,最高纯度级别的水是超纯水(相当于ASTMCAP第1级水)。...
