What is Quantum Yield?
The IUPAC definition of quantum yield (Φ) is the number of a certain event occurring per photon absorbed by the system.1However, it is most commonly written specifically for the emission of light (photoluminescence) by a system2-5 This narrower definition is often simply called quantum yield; with the emission of light being implicit given the context. However, the terms fluorescence, ...

Hydrogen Fluoride Gas Monitor
Hydrogen fluoride, chemical formula HF, is a colorless, highly irritating already at very low ppm levels, corrosive gas and can exist as a fuming liquid. Reaction with water is rapid, producing heat and hydrofluoric acid. Hydrogen fluoride (HF) is used in manufacturing of refrigerants, herbicides, pharmaceuticals, high-octane gasoline, aluminum, plastics, electrical components, and fluorescent ...
