容量法自动滴定在国内已有一些文献进行了报道。有些单位利用72型分光光度计的光电系统作为信号转换,利用给定值的办法实现滴定终点控制。我们对于实现容量法自动滴定中的几个主要问题:信号转换、容量计量、终点控制、显示方式进行了研究。在满足测量精度的要求下,本着提高测量速度、简化分析方法、避开复杂的控制线路等原则,在实验的基础上,研制了LZ—2型钙、镁离子自动滴定仪。该仪器于82年通过
Volumetric automatic titration has been reported in the domestic literature. Some units make use of the optoelectronic system of the 72 spectrophotometer as a signal conversion, using the given value to achieve titration end point control. We have carried on the research to realize several main problems in the automatic titration of volumetric method: signal conversion, capacity measurement, terminal control, display mode. In order to meet the requirements of measurement accuracy, based on the principle of increasing the measurement speed, simplifying the analysis method and avoiding the complicated control circuit, the LZ-2 type calcium and magnesium automatic titrator has been developed. The instrument passed in 82 years
