How does a UV-VIS spectrophotometer work?

WebIn the spectrophotometric analysis in a double beam Uv vis device, when white light passes through the sample and is reflected by a colored substance, a portion of the mixed wavelengths is absorbed. The remaining light beam will be assumed the complementary color to the wavelength of light absorbed. This fact is demonstrated by the color spectrum. WebJan 30, 2024 · In uv spectroscopy, the concentration of the sample solution is measured in mol L -1 and the length of the light path in cm. Thus, given that absorbance is unitless, the units of molar absorptivity are L mol -1 cm -1. However, since the units of molar absorptivity is always the above, it is customarily reported without units.
