› products › uv-visUV-Vis Spectrophotometers Frequently Asked Questions - Light ... In UV/Vis/NIR spectroscopy the ultraviolet (170 nm to 380 nm), visible (380 nm to 780 nm), and near infrared (780 nm to 3300 nm) are used. A nanometer (nm) is 10 -9 meter. Most spectrophotometers are configured as either as UV/Vis instruments that cover the 190 nm to 900 nm (or 1100 nm) wavelength range or UV/Vis/NIR instruments that cover the ... www2.chemistry.msu.edu › UV-Vis › spectrumUV-Visible Spectroscopy Visible and Ultraviolet Spectroscopy. 1. Background. An obvious difference between certain compounds is their color. Thus, quinone is yellow; chlorophyll is green; the 2,4-dinitrophenylhydrazone derivatives of aldehydes and ketones range in color from bright yellow to deep red, depending on double bond conjugation; and aspirin is colorless.

› support › learnHow does the ultraviolet absorption of proteins impact analysis? Spectroscopy of Proteins by UV Absorption. CRAIC Technologies microspectrophotometers are used to acquire spectra of microscopic samples containing proteins, such as individual protein crystals, by their UV absorption. The microspectrophotometer consists of a UV-visible-NIR range microscope integrated with a spectrophotometer.
