摘要
随着自动化程度的提高,需要简单、准确、快速的仪器进行所需要的分析项目。自动电位滴定仪将是一个高效、准确的检测工具,可以通过配备不同的电极,实现电位滴定对氯根含量分析方法的测试。本文以Metrohm905自动电位滴定仪为例,介绐了利用微电脑程序自动控制滴定过程、处理数据和计算结果,最高滴定精度可达0.1ul,分析结果精确,速度快捷,可完成所有经典容量法分析工作。
With the improvement of automation,simple,accurate and fast instruments are needed to carry out the required analysis items.The automatic potentiometric titrator will be an efficient and accurate measuring tool,which can be equipped with different electrodes to test the chlorine content analysis method by potentiometric titration.Metrohm905 automatic potentiometric titration instrument was introduced in our laboratory,and the titration process,data processing and calculation results were automatically controlled by microcomputer program.The highest titration accuracy was up to 0.1ul.The analysis results were accurate and fast,and all the classical volumetric analysis work could be completed.
