【Abstract】 This is a new device for electro-chemical analysis. Made up of integrated circuits, the apparats is stable in quality. Apart from those properties com-mon to all polarographs, it has the following aoutstanding features.The apparatus is small, light, portable and durable. The power consumption is low. Electrolytic Cell in common use for both two-electrode and three -electrode system. Besides, to eliminate the poisonous effect resulting from the use of large quantities of mercury, a mercury film electrode has been used to substitute for the ordinary dropping mercury electrode. It is exceiJent in reproducibility. Thus the working condition is improved. It also allows for a wider range of concentrations of the solute to be determined polarographically.It is used to analyse micro amaunts or traces of metal impurities detected in mineral materials, alloys, chemical products, chemical reagents, waters, soils and medical compounds, It can also be used in electrochemical research work.更多还原
