GFU-202型双光束原子吸收光谱仪(见封2)是我国第一台采用微型计算机控制的商品原子吸收光谱仪。该仪器于83年鉴定,84年投入批试,85年正式生产。目前已有百余台仪器在地质、环保、医学生物学研究、冶金等各部门使用,受到用户欢迎。近年来,微处理机技术推动了大中型分析仪器的发展。在世界市场上各种原子吸收仪器全部配置了微处理机系统,根据其复杂程度不同大致可分为三类:简单的微处理机系统、半自动化的微处理机系统与自动化的微处理机系统。GFU-202属于简单的微处理机系统,具有分析方便,成本低廉的特点。其原理系统如图1所示。该系统由测量系统,微处理机及外围设
GFU-202 dual-beam atomic absorption spectrometer (see seal 2) is China’s first micro-computer controlled commodity atomic absorption spectrometer. The instrument was identified in 83 years, 84 years into the batch test, 85 years of official production. At present, there are already more than 100 instruments in geology, environmental protection, medical biology research, metallurgy and other departments to use, welcomed by users. In recent years, microprocessor technology has promoted the development of large and medium-sized analytical instruments. In the world market, all kinds of atomic absorption instruments are all equipped with microprocessor systems, which can be roughly divided into three categories according to their complexity: simple microprocessor system, semi-automated microprocessor system and automated microprocessor system . GFU-202 is a simple microprocessor system, with the analysis of convenience, low cost features. The principle system shown in Figure 1. The system consists of measurement system, microprocessor and peripherals
