2. Ultraviolet–visible spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet–visible...

   A UV-Vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in a variety of samples.

3. Spectrophotometry - Wikipedia

   en.wikipedia.org/wiki/Spectrophotometry

   Ultraviolet-visible (UV-vis) spectroscopy involves energy levels that excite electronic transitions. Absorption of UV-vis light excites molecules that are in ground-states to their excited-states. [5] Visible region 400–700 nm spectrophotometry is used extensively in colorimetry science. It is a known fact that it operates best at the range ...

   UV-Vis absorption SEC is a recent technique that is continuously evolving. However, many advantages have been observed over other techniques. However, many advantages have been observed over other techniques.

5. UV detectors - Wikipedia

   en.wikipedia.org/wiki/UV_detectors

   An ultraviolet detector (also known as UV detector or UV-Vis detector) [1] [2] is a type of non-destructive chromatography detector which measures the amount of ultraviolet or visible light absorbed by components of the mixture being eluted off the chromatography column.

6. Micro-spectrophotometry - Wikipedia

   en.wikipedia.org/wiki/Micro-spectrophotometry

   Microspectrophotometry is the measure of the spectra of microscopic samples using different wavelengths of electromagnetic radiation (e.g. ultraviolet, visible and near infrared, etc.) It is accomplished with microspectrophotometers, cytospectrophotometers, microfluorometers, Raman microspectrophotometers, etc.

7. Photochemistry - Wikipedia

   en.wikipedia.org/wiki/Photochemistry

   Photochemical immersion well reactor (50 mL) with a mercury-vapor lamp.. Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible (400–750 nm), or infrared radiation (750–2500 nm).
