For example, the concentration of a reactant can be measured by spectrophotometry at a wavelength where no other reactant or product in the system absorbs light.
42.
Spectrophotometry can be used to detect laccases, using the substrates ABTS, syringaldazine, 2, 6-dimethoxyphenol, and dimethyl-p-phenylenediamine.
43.
Named after astrophysicist ( 1895 1975 ), known for his work on spectrophotometry and director of several German observatories, including the discovery site, Heidelberg.
44.
It follows a photometry from 3.6 to 160 micrometers, spectroscopy from 5.2 to 38 micrometers, and spectrophotometry from 5 to 100 micrometers.
45.
In chemistry, "'spectrophotometry "'is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.
46.
A lactose analog is added to the media which is degraded by the beta-galactosidase, producing a colored compound which can be measured quantitatively through spectrophotometry.
47.
In spectrophotometry, the "'Compton edge "'is a feature of the spectrograph that results from the Compton scattering in the scintillator or detector.
48.
The US Office of Scientific Research and Development approached Shell during the summer of 1944, and Robert Brattain assembled a team to study the problem using infrared spectrophotometry.
49.
A simple colorimetric test is possible by adding a lactose analog which is degraded by ?-galactosidase, producing a colored compound which can be measured quantitatively through spectrophotometry.
50.
The analysers, by the association of robotics and spectrophotometry, allowed these last decades a better reproducibility of the results of proportionings, in particular in medical biochemistry and hematology.
