Abstract: A method for analyzing a gas mixture, in which a layer which is configured for the adsorption and/or absorption of components of the gas mixture is exposed to the gas mixture. The method includes cooling the layer from a first to a second temperature and heating the layer from the second to a third temperature. While the layer has the first, second, and third temperature, at least one electrical resistance value of the layer is measured. A method is described in which a first and second layer are exposed to the gas mixture. The first layer is cooled from a first to a second temperature and the second layer is cooled from a third to a fourth temperature. While the first layer has the first and second temperature and the second layer has the third and fourth temperature, at least one electrical resistance value of the respective layer is measured.

Abstract: An attachment device for a sample collection device for obtaining samples from exhaled respiratory air includes an inlet tube, a dip tube for discharging the respiratory air from the sample collection device, and at least a portion of a spiral path. The portion runs into an outlet opening which is designed to conduct the respiratory air to the sample collection device.

Abstract: A device for analyzing substances in a sample on the basis of a measurement of nuclear magnetic resonances including a magnetic field device configured to generate a magnetic field. The device is configured such that, in order to detect magnetic resonances induced in the sample by the generation of the magnetic field, provision is made of at least one magnetic field sensor which comprises at least one sensitive component with diamond structures. The diamond structures have nitrogen vacancy centers.

Abstract: A hand-held measuring instrument is used for detecting hidden mold damage in interior spaces. The measuring instrument includes at least one collection unit configured to intake at least of one interior space sample, at least one buffer unit, at least one immunological test unit, an evaluation unit and a control panel. The at least one buffer unit has a first compartment and a second compartment.

Abstract: A food packaging arrangement (1) comprising a packaging (2) and a chemical composition (4) which, by reaction with a breakdown product of the food (3) in question, forms a light-emitting or fluorescent compound or emits light.

Abstract: A device, a method, and a use thereof for detecting a concentration of a gas or of a gas component. The device as a gas sensor includes at least one sensor element including a gas-sensitive layer and a heating element for heating the gas-sensitive layer. The heating element is able to heat the sensitive layer to a desired temperature prior to the detection and/or is able to maintain it at a desired temperature during the detection. The heating element allows the gas-sensitive layer to be outgassed if needed, so as to allow absorption again. To heat the heating element, there is a first contacting to which a first voltage may be applied. Moreover, subsequent to the heating step, a second voltage may be applied to the sensor element or to the gas-sensitive layer for measured value detection with the aid of a second contacting.
