火焰光度计是实验室进行钾、钠定量分析的常用仪器,广泛用于农业上的土壤肥力及植株养份分析、医疗上临床化验及病理研究、以及工业产品的分析等方面。现以上海分析仪器厂生产的6400型火焰光度计为例,结合本人多年检修实际,谈谈该仪器常见故障的调修。一、仪器结构该仪器由气路控制系统、喷雾燃烧室、微电流放大器和稳压电源四部份组成。整机线路如图所示,由微电流放大器和稳
Flame photometer laboratory commonly used potassium, sodium quantitative analysis of commonly used instruments, widely used in agricultural soil fertility and plant nutrient analysis, medical clinical laboratory and pathological studies, as well as industrial products analysis and so on. Now the 6400 flame photometer produced by Shanghai Analytical Instrument Factory is taken as an example. Combining with the actual situation of overhauling for many years, we talk about the adjustment of the common faults of this instrument. First, the instrument structure The instrument from the gas control system, spray combustion chamber, micro-current amplifier and power supply composed of four parts. The whole circuit shown in the figure, by the micro-current amplifier and stability
