Abstract
Disclosed is a method for automatic qualitative classification of chemical substances and substance mixtures according to olfactory characteristics. The inventive method comprises the following steps: a) measurement of human sensory predetermined reference samples by means of a sensor system comprising at least two sensors; b) creation of at least one measuring value for the respective sample(s)(n); c) formation of one or several olfactory characteristics on the basis of the measuring values determined for the reference samples; d) measurement of a sample of a substance or substance mixture by means of the above-mentioned sensor system, whereby at least one measuring value of the sensor system associated with the substance/substance mixture is obtained; e) determination of the olfactory characteristics of the substance/substance mixture by the relative position of the associated measuring value(s) in or in relation to one of the clusters defined in step (c). The inventive method can be used for production control of chemical processes according to olfactory characteristics, whereby samples of the substance mixture are collected during at least one point of said process, said samples are measured by means of said classification method and the measuring values thus obtained are used to control the amount of at least one used raw material, additive or auxiliary agent by means of a suitable control circuit.
