The reaction rate is pH dependent, and slightly alkaline conditions achieved by adding a weak base, e.g. sodium salicylate, will produce brighter light.Developed by American Cyanamid in the 1960s, the formulation containing CPPO, a fluorescer, and a glass capsule containing hydrogen peroxide and a base catalyst, all in dialkyl phthalate solvents, was marketed as Cyalume.
Chemiluminescence in aqueous system is mainly caused by redox reactions. [4] Chemiluminescence after a reaction of hydrogen peroxide and luminol. Luminol in an alkaline solution with hydrogen peroxide in the presence of iron or copper, [5] or an auxiliary oxidant, [6] produces 3-aminophtalate in an excited state, which exhibits ...
Luminol (C 8 H 7 N 3 O 2) is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent.Luminol is a white-to-pale-yellow crystalline solid that is soluble in most polar organic solvents but insoluble in water.
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
the central organic synthesis reagent for hydroboration Dicyclohexylcarbodiimide: an organic compound; primary use is to couple amino acids during artificial peptide synthesis Diethyl azodicarboxylate: a valuable reagent but also quite dangerous and explodes upon heating Diethyl ether: organic compound; a common laboratory solvent Dihydropyran
FIA is an automated method of chemical analysis in which a sample is injected into a flowing carrier solution that mixes with reagents before reaching a detector. Over past 30 years, FIA techniques developed into a wide array of applications using spectrophotometry , fluorescence spectroscopy , atomic absorption spectroscopy , mass spectrometry ...
