示波极谱仪的微机数据采集系统

Microcomputer Data Acquisition System for Oscillopolarography

用ADC0809为A/D转换器,联同SHARP PC—1500袖珍计算机,组合成示波极谱仪的数据采集系统。实现了示波极谱仪的电子计算机采数。该系统速度快,准确度高,并可用逐点相减法彻底消除残余电流。现已用于化探样品中钨钼的极谱催化波测定。

A microcomputer data acquisition system for oscillopolarography consists of an ADC 0809 A/D converter and a SHARP PC-1500A computer. The system is characterized not only by high speed and accuracy, but also capable of complete elimination of residual current by the point to point method. The system has been applied to the determination of tungsten and molybdenum in geological samples by catalytic polarography.
