Olfactometry is the measurement of smell. It is a scientific discipline concerned with quantifying the intensity, quality, and hedonic tone of odors. Olfactometry encompasses a variety of techniques and methodologies used to assess the olfactory properties of substances, environments, or products. This field is crucial in many areas, including environmental monitoring, food and beverage quality control, perfumery, and medical diagnostics.

The primary goal of olfactometry is to provide objective and reproducible data about smell. This can involve determining odor thresholds, which are the minimum concentrations of an odorant that can be detected by the human nose. It also involves assessing odor intensity, often using scales that relate perceived strength to concentration. Furthermore, olfactometry can be used to characterize odor quality, describing the specific smell (e.g., floral, fruity, pungent) and its hedonic value, indicating whether the smell is pleasant or unpleasant.

Common methods in olfactometry include dynamic olfactometry, where a controlled flow of air containing a specific concentration of odorant is presented to a panel of trained assessors. Sensory panels, composed of individuals with heightened olfactory sensitivity and trained to evaluate odors consistently, are often employed. Instrumental methods, such as gas chromatography-mass spectrometry (GC-MS), can identify and quantify odorant compounds, complementing sensory evaluations. The data generated through olfactometry helps in setting odor limits, developing new products, and understanding the impact of odors on human well-being and the environment.
