    • 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.
    • 它是由气味公开的特征在于用于自动的,化学物质和物质混合物的定性分类,其包括以下步骤的方法:1)humansensorisch预定的参考样本的测量通过一个传感器系统,包括至少两个传感器的装置; B)用于相应的(n)的参考样品(一个或多个)产生至少一个测量值; c)形成一个或基于所确定的参照样品的测量值更气味特性簇; D)借助于测量物质或物质混合物的一个样品,所述的传感器系统,至少一个与所述传感器系统的测量值的物质/相关联的获得; E)在步骤(c)中所定义簇通过在或向相应的测量值(一个或多个)的/相对位置物质/物质混合物的气味特性的测定。 本发明的方法可以通过一个合适的控制电路的装置被用于化学过程气味特性的生产控制,其特征在于至少一个主体,以在过程中除去,该材料混合物的样品中,样品通过的分类方法来测量,并且将由此获得的测量值,用于控制至少使用量 的原料,添加剂或辅助剂使用。
