    摘要: A method and a device for determining a physiological state of a test subject is presented. In the method, a first VOC pattern is determined from a first test medium and a second VOC pattern is determined from a second test medium. The first VOC pattern has a first group of VOCs and includes one or more VOCs detected in the first test medium and their respective concentrations. The second VOC pattern has a second group of VOCs and includes one or more VOCs detected in the second test medium and their respective concentrations. Subsequently, the first and the second VOC patterns are combined to obtain a VOCome pattern. Finally, the VOCome pattern is compared to a reference pattern. The reference pattern comprises a collection of different VOCs and concentrations of each of the different VOCs and represents a predicted known physiological state of the test subject.

    摘要: The invention relates to a gas sensor which is used to detect ammonia by detecting and evaluating conductivity variations on semi-conductive metal oxides, comprising: a substrate, a gas sensitive layer made of a semi-conducitve metal oxide, a catalytic filter which is disposed in front of the metal oxide, said filter being used to convert ammonia, contained in the measuring gas, into a NO/NO2 mixture or to only NO2, measuring electrodes which are arranged on the surface of the substrate in order to detect conductivity variations in the semi-conductive metal oxide which is at least sensitive to NO/NO2, a controllable electric heating device which is used to adjust predetermined temperatures at least for the semi-conductive metal oxide, whereby the formed NO/NO2 can be guided to the metal oxide and the content of ammonia in the measuring gas can be determined from the NO/NO2-measurement by means of the semi-conductive metal oxide.
