UV-Vis absorption experiments for chemists, biochemists, biologists, physicists and general scientists. Sim4T lets your students work their way through carefully designed experiments using a UV-Vis absorption spectrometer simulator.UV-Vis Absorption Spectroscopy
UV-Vis spectroscopy has many uses across science such as in monitoring the progress of a chemical reaction, through analysis of pharmaceutical substances and in biology, in investigation of proteins. UV-Vis spectroscopy involves measurement of the fraction of incident electromagnetic radiation that is either absorbed or transmitted by a sample and this process can be described by the Beer-Lambert Law. One of the key features of this law is that the absorbance (the radiation that is absorbed by the sample) is related to the concentration of the absorbing species present which is important in analytical science and quantitative analyses.
