摘要
设计了一种低成本、高精度的三电极分析装置。此装置主要包括前端模拟电路部分、数字电路处理和上位机界面,利用TLV2262,TLV2264,ICL7650S搭建了前端模拟部分,主控芯片C8051F020完成了电压反馈控制和电流信号的采样及上位机通信。亚铁氰化钾氧化峰实验数据证实此装置运行稳定,可用于类似的实验中。
We design a low-cost and high-precision three-electrode analysis device. It includes front-end analog circuit, digital circuit and PCsoftware. Its front-end analog circuit consists of TLV2262, TLV2264and ICL7650S. Chip C8051F020 performs voltage feedback control, current signal sampling and communication with PC. Experimental data of potassium ferrocyani oxidation peak show that this device is stable and can be used in similar experiments.
