计算机辅助流动注射分析仪的研制

A Microprocessor-based Instrument for Flow Injection Analysis

摘要: 研制微处理器控制的流动注射分析仪。仪器配微打印机,自动完成取样、进样、采集处理信号、打印显示结果等分析过程。仪器自成独立系统可与多种分光光度计联用。分别对100 ppm和800 ppm的K_2Cr_2O_7连续测定40次,相对标准偏差分别为1.42%和1.09%。

Abstract: A microprocessor-based instrument for flow injection analysis was designed and assembled. Using Z80 CPU as processor, the instrument consists of a 24 line microprinter, 8 bits analogue to digital converter, 6 digit 7 segment display and other relational h
