JP-1A型示波极谱仪是我国六十年代的产品,现仍广泛应用,但其性能已不能很好适应当前教学、科研和生产部门的要求,特别是不能满足极谱机理与电极动力过程研究的需要。云南大学化学系部分教师,经过认真研究,对仪器扫描电压速度、扫描时间、休止时间、极化电位范围和导数电路作了改进,并增加了二次导数功能,设计为独立单元,组成一整机装置。该装置配上原示波极谱仪,使仪器功能更全,性能更好,灵敏度、分辨率及抗前还原物质能力等主要指标均达到较先进的水平。新功
JP-1A oscilloscope is a product of China’s sixties, is still widely used, but its performance can not well adapt to the current teaching, research and production department requirements, in particular, can not meet the polarographic mechanism and electrode power The need for process research. Some teachers of the Department of Chemistry of Yunnan University, after careful study, made improvements on the instrument scanning voltage speed, scanning time, rest time, polarization potential range and derivative circuit, and added the second derivative function, designed as a separate unit to form a whole Machine installation. The device coupled with the original oscilloscope polarography, the instrument features more complete, better performance, sensitivity, resolution and anti-pre-reduction of substances and other major indicators have reached a more advanced level.
