An appliance is disclosed for measuring at least one gas analyte in exhaled air. In at least one embodiment, the appliance includes an inlet opening for the introduction of exhaled air (mouthpiece), at least one measuring chamber for receiving a sensor unit, and a conduit which provides a fluid connection from the opening to the measuring chamber, and wherein, depending on the gas analyte that is to be measured, a sensor unit with a suitable gas sensor can be introduced into the receiver.
摘要:
Example embodiments relate to a device for measuring nitrogen monoxide in exhaled air by a gas sensor unit with at least one gas sensor. A device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide may be included. The device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide includes a non-consuming catalyst for catalyzing the oxidation of nitrogen monoxide to nitrogen dioxide.

摘要:
An assembly and a method for filtration are disclosured, which are suitable in particular for the filtration of cells, for example tumor cells, from a sample, for example a blood sample. In the method, a pressure differential between the pressure upstream and the pressure downstream of a filter is determined; and the pressure differential between upstream and downstream of the filter is adjusted such that the pressure differential does not exceed a predetermined value.
摘要:
An assembly and method are disclosed for the filtration of a liquid and the use thereof, wherein a supporting body is designed in a recess of a carrier and a filter membrane lies flat on the supporting body. The filter membrane and the supporting body are designed to be permeable to liquids and thus serve as filters, in particular for filtering tumor cells from blood. The carrier can having standard shapes of an object carrier for microscopy and the filtration residue on the filter membrane can be easily handled and examined in the microscope. As a result of the filter membrane lying level on the supporting body, the filtration residue can be particularly well examined microscopically.
