目前,化学分析容量法所用的容积为25毫升、50毫升各种类型滴定管,是使用广泛,用量较大的一种容量分析仪器。这些常量滴定管分度值为0.1毫升。另一种精密型滴定管,分度值为0.05毫升,但有效容积小,只能用于微量组分的化学分析。为了普遍提高化学分析工作质量和分析结果的精度,我们将常用滴定管加以改革,设计一种新型的常量精密滴定管,经试用效果很好。我们对国内主要化工产品的成分分析方法和我厂化工产品多年来的化学分析数据进行研
At present, the capacity of chemical analysis volumetric method for the volume of 25 ml, 50 ml of various types of burettes, is widely used, a large amount of capacity analysis instrument. These constant burets have a graduation of 0.1 ml. Another type of precision burette, graduation value of 0.05 ml, but the effective volume of small, only for the chemical composition of trace components. In order to generally improve the quality of chemical analysis and analysis of the accuracy of the results, we will be buret to be used to reform the design of a new type of constant precision burette, the trial results very well. We analyze the composition of major chemical products and chemical products in our chemical analysis over the years to carry out research data
