【摘要】 <正> 国内微机化电位溶出分析仪的研制已有不少报道,但功能强的尚不多见.本文在自制EA-1型微机化电化学分析仪的硬件基础上,开发了功能强,使用灵活,操作简便的多扫描电位溶出分析(MPSA)软件,并初步应用于碳纤维微电极的研究,有关这方面的工作尚未见报道.MPSA的原理是利用被分析物质在工作电极表面反复沉积——溶出来大大增强响应信号.研究结果表明,在MPSA中微电极比宏电极优越.更多还原

【Abstract】 A software with excellent performance for multiple-scanning potentiometric stripping ana-lysis (MPSA) has been developed.The software is written in BASIC language and 6502 Assembler language,and has abundant data processing and graphic editing functions.A multichannel data acquisition technique is used and a high acquisition rate of 31 kHz is achieved by the optimiza-tion of the software.The system has been used with satisfation for the study of MPSA using carbon fiber mieroelectrode.更多还原
