odor detection threshold

Olfactometers are used to gauge the odor detection threshold of substances.

Tribromoanisole has a very low odor detection threshold.

A human's odor detection threshold is variable.

Its odor detection threshold is very low and it is one of the chemicals with major influence on the quality of drinking water.

The odor detection threshold for phosgene is 0.4 ppm, four times the threshold limit value.

Trichloroanisole has a very low odor detection threshold (single parts per trillion), so even very minute amounts can be detected.

This isomer is also the most potent of all eight with an odor detection threshold of 10 ng/L in model wine.

Frank Jones, an American psychologist, published a paper demonstrating the interplay between parameters of sniffing and odor detection thresholds.

The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell.

Even though these compounds exist in less than 1% quantity of rose oil, they make up for slightly more than 90% of the odor content due to their low odor detection thresholds.

The odor detection threshold and the odor recognition threshold are absolute thresholds; the first is the minimum concentration at which an odor can be detected without any requirements to identify or recognize the stimulus, while the second is the minimum concentration at which a stimulus can be identified or recognized.
