UV-Vis是英文Ultraviolet-Visible Spectroscopy的缩写,即紫外-可见光谱。它是一种光谱分析技术,主要利用紫外光和可见光的波长范围,通过测定样品溶液的吸光度,对物质进行定性和定量分析。UV-Vis具有广泛的应用领域,如环境监测、食品安全、化妆品分析、药物研发等。UV-Vis光谱是物质分子吸收光子后产生的结果。当光照射...

UV-VIS spectroscopy is considered as the most important spectrophotometric technique that is most widely used for the analysis of variety of compounds. This technique works on the basis of the measurement of interaction of electromagnetic radiations (EMR) with matter at particular wavelength. In this...
