紫外—可见分光光度计是进行物质成分分析的有力工具,它广泛地应用在工业、农业、医药卫生等各个领域的科学研究和化验分析中。紫外—可见分光光度计的基本结构如图1所示。它的基本原理是从光源发出的连续辐射,经过单色器分光,以单色光的形式照射在样品上,单色光被样品吸收后,由检测器接收透过的光,最后由信号指示系统指示出样品的透光率或吸光度。紫外—可见分光光度计按照照在样品室的单色光是单光束还是双光束(一束照到样品池,一束照到参比
UV-visible spectrophotometer is a powerful tool for the analysis of material composition, which is widely used in scientific research and laboratory analysis in various fields such as industry, agriculture, medicine and health. UV - visible spectrophotometer of the basic structure shown in Figure 1. Its basic principle is continuous radiation emitted from the light source, after monochromator spectroscopy, in the form of monochromatic light irradiation on the sample, the monochromatic light is absorbed by the sample, the detector receives the transmitted light, and finally by the signal The system indicates the light transmittance or absorbance of the sample. UV - visible spectrophotometer according to the sample room monochromatic light is a single beam or double beam (a beam of light to the sample cell, a photo of the reference
