The chloride ion is a well known quencher for quinine fluorescence. [2] [3] [4] Quenching poses a problem for non-instant spectroscopic methods, such as laser-induced fluorescence. Quenching is made use of in optode sensors; for instance the quenching effect of oxygen on certain ruthenium complexes allows the measurement of oxygen saturation in ...
In chemistry, a dark quencher (also known as a dark sucker) is a substance that absorbs excitation energy from a fluorophore and dissipates the energy as heat; while a typical (fluorescent) quencher re-emits much of this energy as light. [1] Dark quenchers are used in molecular biology in conjunction with fluorophores.

Black Hole Quencher 1 (BHQ1) is an example of dark quencher, which is used to quench green and yellow dyes, such as 6-carboxyfluorescein (6-FAM), tetrachlorofluorescein (TET), and hexachlorofluorescein (HEX).
For diffusion-limited quenching (i.e., quenching in which the time for quencher particles to diffuse toward and collide with excited particles is the limiting factor, and almost all such collisions are effective), the quenching rate coefficient is given by = /, where is the ideal gas constant, is temperature in kelvins and is the viscosity of ...
