Structural Biochemistry/Proteins/Measuring Enzymatic Activity Using Spectroscopy - Wikibooks, open b What is an Enzyme? [edit] Enzymes are powerful biological catalyst. Catalysts speed up a reaction but are not consumed in the reaction. Enzymes are thus essential for such bodily functions as digestion because otherwise, these reactions would occur at too
Material properties of diamond - Wikipedia, the free encyclopedia Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. Diamond is an optically isotropic crystal that is transparent to opaque. Owing to its strong covalent bonding, diamond is
Detectors of Light - Chemwiki - ChemWiki: The Dynamic Chemistry E-textbook - Chemwiki Quantum Efficiency The quantum efficiency, \(\eta\), for a photodiode is generally a function of wavelength, and is defined as \(\eta\) = Number of photoelectrons liberated/Number of incident photons The value of \(\eta\
What difference between pda and uv detector in hplc PDA - Photo diode array UV- Ultra violet with use of PDA detector, we can measure the area or height of particular peak at different wavelengths ranging from 200 to 800 nm by injecting the solution at once. Where as in uv detector we can measure the area
