摘　　要：本文介绍高灵敏度多功能的901—PA分析仪。该仪器采用国产静电计管作微电流检出元件,设有高度的稳零电路。最小检测电流为0.1PA,漂移±2mV/hr,扫描范围为±5V,且具有多阶半微分功能,适合于电分析化学中的微电极研究。A highly-sensitive and multifunction microelectrode voltammeter is described. The key elements of its I/V converter are a DC-4BJ static electronic tube and glass encapsulated film resistors. The minimum measurable current is ±0.1 pA and the potential scan range is ±5V. The instrument has the capability of doing multistep semidifferentiation and is suitable for microelectrode research in electro-analytical chemistry.
