A diluted odorous mixture and an odor-free gas—n-Butanol—as a reference are presented from sniffing ports to a group of panelists who are sensitive in odor perception. To collect an odor sample, the samples are collected using specialized sample bags, which are made from an odor free material, e.g., Teflon. The most accepted technique for ...
Articles relating to odor, caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive by their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor.
The Lady and the Unicorn, a Flemish tapestry depicting the sense of smell, 1484–1500. Musée national du Moyen Âge, Paris.. Early scientific study of the sense of smell includes the extensive doctoral dissertation of Eleanor Gamble, published in 1898, which compared olfactory to other stimulus modalities, and implied that smell had a lower intensity discrimination.

In all industries, odor assessment is usually performed by human sensory analysis, by chemosensors, or by gas chromatography.The latter technique gives information about volatile organic compounds but the correlation between analytical results and mean odor perception is not direct due to potential interactions between several odorous components.
Smell may refer to; Odor, airborne molecules perceived as a scent or aroma; Sense of smell, the scent also known scientifically as olfaction "Smells" , an episode of Bottom; The Smell, a music venue in Los Angeles, California; Code smell, any characteristic of a program that possibly indicates a deeper problem
Odorous steam is released from chimneys due to the treatment process happening in the mill, the smell may vary from vinegar to grease trap. [13] EPA submitted four remedial notices since 2020 and fined the company $9,000 for failing to stop the smell a year later. [14] Mid 2023, odour emissions were still monitored by EPA around the Visy site.
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
