Irradiated tyrosine underwent a significant increase of the absorbance and finally yielded an exponential absorption spectrum, with close resemblance to the behaviour of a protein-rich and humic-poor sample of subterranean water. In contrast, irradiated humic acids underwent photobleaching in a similar ...
The application of spectral analysis to water quality monitoring is an important developing trend in the field of modern environment monitoring technology.The principle and characteristic of water quality monitoring technology based on UV-Vis spectrum analysis are briefly reviewed.And the research status ...

In UV-Vis spectroscopy, light passes through the sample, and certain wavelengths are absorbed, causing electronic transitions. The resulting absorption spectrum is recorded and analysed to determine the presence and concentration of specific substances. It is a widely used analytical technique, and its...
The basicity of alkali-metal-exchanged (Na, K, Cs) zeolites X and Y was probed by UV−vis diffuse reflectance spectroscopy of adsorbed iodine. The observed blue shift in the visible absorption spectrum of adsorbed iodine, compared to gaseous iodine, correlated well with the negative charge on...
271 Effective description of the conformational behavior of saccharides in explicit water can be achieved using MD, either classical or quantum, such as Car-Parrinello (CPMD).272 Spectra are then typically calculated for a set of solute-solvent clusters, with the final spectrum represented as an ...
Protein samples in RIPA buffer should be quantified via the Pierce Protein 660 or BCA colorimetric assays using a full spectrum NanoDrop model. Find additional tips, troubleshooting help, and resources within ourProtein Purification and Isolation Support Center. ...
Ultraviolet and visible spectroscopy deals with the recording of the absorption of radiations in the ultraviolet and visible regions of the electromagnetic spectrum. The ultaviolet region extends from 10 to 400 nm. It is subdivided into the near ultraviolet (quartz) region (200–400 nm) and the...
Conveniently, many API show a pronounced absorption in the UV spectrum, between 230–380 nm. Many exclusively or additionally show absorption in the visible part of the spectrum, (380–780 nm) so this wavelength range should also be considered for extrudate characterization, which is shown in th...
