摘要
在一个新设计的以汞为电极流动注入分析体系中,蠕动泵不能提供恒定流速,因而常用的时钟法已很难准确地控制体系,为此,采用了光敏耦台器来代替时钟控制整个分析体系,与时钟法比较,流动体系的流速对光敏电路的影响不大,因而系统控制过程更接近该体系的设计要求。
In a flow injection analytical system with newly designed mercury electrodes, the conventional peristaltic pump can't provide 8 constant (low rate,such that the commonly used time-control didn't work well. A photo sensetive interrupter was suggested to replace the timer for the system control in the on-line formation of an electrochemical analytical cell with the new murcury electrodes and in the electrochemical measurements. Comparing with the timer,the photo sensetive interrupter can ignore the fluctuation from the var-ity of the flow rate,and make the control procedure more relable and more satifactory to the requirement of the system design.
