    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.

    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.

  4. 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 ...

  5. Variable pathlength cell - Wikipedia

    en.wikipedia.org/wiki/Variable_pathlength_cell

    In ultraviolet-visible spectroscopy or spectroscopy in general a 1 cm pathlength cuvette is used to measure samples. The cuvette is filled with sample, light is passed through the sample and intensity readings are taken. The slope spectroscopy technique can be applied using the same methods as in absorption spectroscopy.

  6. Optical spectrometer - Wikipedia

    en.wikipedia.org/wiki/Optical_spectrometer

    In modern spectrographs in the UV, visible, and near-IR spectral ranges, the spectrum is generally given in the form of photon number per unit wavelength (nm or μm), wavenumber (μm −1, cm −1), frequency (THz), or energy (eV), with the units indicated by the abscissa.

  7. Spectronic 20 - Wikipedia

    en.wikipedia.org/wiki/Spectronic_20

    The Spectronic 20 is a brand of single-beam spectrophotometer, designed to operate in the visible spectrum [1] across a wavelength range of 340 nm to 950 nm, with a spectral bandpass of 20 nm. [ 2 ] [ 3 ] It is designed for quantitative absorption measurement at single wavelengths. [ 1 ]

    en.wikipedia.org/wiki/Google_Scholar

    Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. . Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other ...

  9. UV detectors - Wikipedia

    en.wikipedia.org/wiki/UV_detectors

    The variable UV-Vis absorbance detector's optical bench is showing how the flow cell is positioned after the optical system, including the monochromator, which typically has a physical slit and a moving grating, so it is illuminated by a selected wavelength, reaching a photo-diode.
