2. Ultraviolet–visible spectroscopy - Wikipedia

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

   An example of a UV-Vis readout. UV-Vis can be used to monitor structural changes in DNA. [8] UV-Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of diverse analytes or sample, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules. Spectroscopic analysis is ...

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 ...

4. UV detectors - Wikipedia

   en.wikipedia.org/wiki/UV_detectors

   The most common UV-Vis detectors used are variable wavelength detectors (VWD), photo diode array detectors (PDA), and diode array detectors (DAD). [4] Variable wavelength detectors decide in advance which wavelength is needed for the detection. Its absorbance as function of time is collected in a graphic format called a chromatogram. [5]

5. SPC file format - Wikipedia

   en.wikipedia.org/wiki/SPC_file_format

   The SPC file format is a file format in which all kinds of spectroscopic data, including among others infrared spectra, Raman spectra and UV/VIS spectra. The format can be regarded as a database with records of variable length and each record stores a different kind of data (instrumental information, information on one spectrum of a dataset ...

6. Fourier-transform infrared spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Fourier-transform_infrared...

   The goal of absorption spectroscopy techniques (FTIR, ultraviolet-visible ("UV-vis") spectroscopy, etc.) is to measure how much light a sample absorbs at each wavelength. [2] The most straightforward way to do this, the "dispersive spectroscopy" technique, is to shine a monochromatic light beam at a sample, measure how much of the light is ...
