Application to industrial odor problems
Olfactometric analysis or odor measurement by sensory analysis

Characteristic elements of an odor source

We have seen that measuring the dilution factor at the perception threshold of a gas sample gives direct access to the value of the odor concentration of the gas, a characteristic variable of the effluent under study.

Note 1: as the measurement of K ₅₀ (NF X 43-101 standard) or Z _ITE (EN 13725 standard) is based on diluting the sample with odourless air (see §
