定量分析一般采用常量法,其消耗化学药品相当可观。在工农业生产大跃进的形势下,分析工作也相应增加,造成分析用化学药品供不应求。拟将常量分析全部改用半微量分析,但考虑到半微量分析天平普通使用也有困难,故尽量避免重量分析而设法改用容量分析。半微量容量分析的优点是在于所消耗的药品仅为常量法的5—10%;现将我们在钢铁分析中采用半微量分析实验略述如下:
Quantitative analysis is generally used constant method, which consumes considerable chemical. Under the situation of great leap forward in industrial and agricultural production, the analysis also increased correspondingly, causing the demand for analytical chemicals to fall short of demand. It is proposed that all of the constant analysis be switched to semi-trace analysis, but taking into account the common use of semi-trace analysis balances is also difficult, we try to avoid weight analysis and try to use capacity analysis instead. The advantage of semi-micro capacity analysis is that the consumption of drugs is only 5-10% of the constant method; now we use the semi-micro analysis of steel analysis experiments outlined below:
