How does a uv spectrophotometer work
WebSpectroscopy is based on the interaction between light and matter. When the matter absorbs the light, it undergoes excitation and de-excitation, resulting in the production of a spectrum. When matter absorbs ultraviolet radiation, the … WebThe UV–Vis scan spectrophotometer is used for scanning the absorbance to detect the unique wavelength maxima of pigment molecules, while FTIR analysis is used to detect or elucidate the functional groups within the pigment’s molecular structure (Ahmad et al., 2012).
