一、概况 1.标准试剂标准试剂是衡量其他物质化学量的标准物质。它是化学试剂的许多门类中的一类。在我国习惯上将容量分析用的标准试剂和相当于IUPAC的C级的pH标准试剂称为基准试剂,而将其他的称为标准试剂。标准试剂和基准试剂总的称为标准试剂。标准试剂按其衡量物质的不同,也就是按其用途的不同,又进一步分成了许多类别。 2.标准试剂的“级”我国生产的标准试剂中有一部份品种分两级,高一级的是由国家测定和发放的标准,即第一基准;低
First, an overview 1. Standard Reagents Standard Reagents is a measure of the amount of other chemical substances standard material. It is one of many categories of chemical reagents. In our country, the standard reagent for volumetric analysis and the pH standard reagent equivalent to CUP of IUPAC are referred to as reference reagents in our country, and others are called standard reagents. Standard reagents and reference reagents are generally called standard reagents. Standard reagents according to their measurement of different substances, that is, according to their different uses, is further divided into many categories. 2. Standard reagent “level” China’s standard reagents produced in some varieties in two levels, a higher level by the state determination and payment of the standard, the first benchmark; low
