    Definition any process which decreases the fluorescence intensity of a given substance Reference COM-EN, based on:Wikipedia > Quenching (fluorescence), http://en.wikipedia.org/wiki/Quenching_%28fluorescence%29 [28.3.2018]
    Comment A variety of processes can result in quenching, such as excited state reactions, energy transfer, complex-formation and collisional quenching. As a consequence, quenching is often heavily dependent on pressure and temperature. Molecular oxygen, iodide ions and acrylamide are common chemical quenchers. The chloride ion is a well known quencher for quinine fluorescence. Quenching poses a problem for non-instant spectroscopic methods, such as laser-induced fluorescence.

    quenching
    en
    Definition cooling of a hot exhaust gas before it enters a pollution scrubber Reference COM-Terminology Coordination, based on:Wikipedia, Quenching (scrubber), https://en.wikipedia.org/wiki/Quenching_(scrubber) [28.10.2015]
    Comment Hot gases (those above ambient temperature) are often cooled to near the saturation level. If not cooled, the hot gas stream can evaporate a large portion of the scrubbing liquor, adversely affecting collection efficiency and damaging scrubber internal parts. If the gases entering the scrubber are too hot, some liquid droplets may evaporate before they have a chance to contact pollutants in the exhaust stream, and others may evaporate after contact, causing captured particles to become reentrained. In some cases, quenching can actually save money. Cooling the gases reduces the temperature and, therefore, the volume of gases, permitting the use of less expensive construction materials and a smaller scrubber vessel and fan.
