An olfactometer is an instrument used to detect and measure odor dilution. Olfactometers are used in conjunction with human subjects in laboratory settings, most often in market research, to quantify and qualify human olfaction. [1] Olfactometers are used to gauge the odor detection threshold of substances. To measure intensity, olfactometers ...
The device combines a digital display with four small fans that direct an emitted odor to a specific spot on the screen. The fans operate at a very low speed, making it difficult for the user to perceive airflow; instead they perceive the smell as coming directly out of the screen and object displayed at that location.

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.
Scentography is the technique of creating and storing odor by artificially recreating a smell using chemical and electronic means.. DigiScents Inc was among the more recent pioneers of the technology, developing DigiScent (later iSmell) in 1999 as a device that would plug into a computer's USB port and generate scents dependent on the online content being viewed.
Such an apparatus is often called an electronic nose or e-nose. The development of machine olfaction is complicated by the fact that e-nose devices to date have responded to a limited number of chemicals, whereas odors are produced by unique sets of (potentially numerous) odorant

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 ...
