交流示波极谱滴定仪(简称示波滴定仪)是利用交流示波极谱曲线dE/dt=f(E)上切口的出现或消失指示容量分析滴定终点的电分析仪器。图1是LS-1型交流示波极谱滴定仪方框图。该仪器在络合、沉淀、中和滴定和有机物的容量分析中能迅速、直观、准确地确定滴定终点,溶液颜色和沉淀 AC oscilloscope polarographic titrator (referred to as oscillometric titrator) is the use of AC oscillopolarography curve dE / dt = f (E) incision on the appearance or disappearance of capacity analysis of titration end point of the electrical analysis instrument. Figure 1 is a block diagram of an LS-1 AC oscilloscope. The instrument in the complexation, precipitation, and titration of the capacity of organic matter in the capacity analysis can be quickly, intuitively and accurately determine the end of titration, solution color and precipitation
