UV/VIS/NIR Spectroscopy is used to determine analyte concentration by measuring light absorption across the ultraviolet and visible light wavelengths.
Absorption spectroscopy includes UV-Visible spectroscopy. For qualitative, quantitative, and structural study of a material in solution, absorption spectroscopy in the UV-visible region is one of the oldest and most widely used techniques in pharmaceutical analysis. The spectrum created by the substance...
UV-visible-NIR spectroscopy Aspectrophotometeris a device measures the intensity of electromagnetic energy at each wavelength of light in a specified region. A UV-visible-NIR spectrophotometer, such as used in CRAIC microspectrophotometers, operate in the ultraviolet, visible and near infrared regions....
