摘　　要：目前我国生产的极谱仪，虽然类型不少，但是应用性比较专一，按照一般教学和科研工作的实际需要，希望极谱仪能有较多的用途。例如，高等学校仪器分析实验课程中，需要进行经典极谱、单扫(示波)极谱、催化极谱和溶出伏安法实验；在物理化学实验课程中，Model AD-2 polarograpn constructed from operational amplifier is detailed in this paper. It has broader range of variable sweep voltage, adjustable linear scan velocity, comprehensive compensators and a potentiostat for compensating voltage drop as iR and electrode polarization. Therefore besides general two-electrodes system, it can also be used for the three-electrodes system, which is needful when analysis has to proceed in very dilute solutions, or in a bit of sample, and specially when the peak potential is needed to be measured accurately. Model AD- 2 polarograph is equipped with a Model TJ-1 Electroanalytical Table, which includes nine electrodes and can be used in most voltammetries.
