仪表式分光光度计依据物质对光的选择性吸收,对样品进行定性定量分析,在农业上,广泛用于农化分析、生化分析、农产品品质分析及饲料营分析等,是实验室常备仪器,仅721型分光光度计我校就有70多台。仪表式分光光度计,如721型、XG-125型等,多采用单光束、自准式光路,用棱镜作单色器,用光电管作检测器,用磁电式仪表作显示器,结构简单,操作方便。随
Instrumental spectrophotometer based on the selective absorption of light on the sample qualitative and quantitative analysis, in agriculture, widely used in agrochemical analysis, biochemical analysis, quality analysis of agricultural products and feed camp analysis, is a laboratory equipment, Only 721 spectrophotometer I have more than 70 Taiwan. Instrumentation spectrophotometer, such as 721, XG-125 and so on, the use of single beam, self-aligning optical path, prism for the monochromator, photoelectric detector for the detector, magnetic meter as a display, simple structure , Easy to operate.
