Abstract: The invention relates to a method for analyzing components of exhaled air with the aid of electrochemical sensors and/or biosensors. Said components are determined by measuring and evaluating signals generated by one or several of the sensors during contact with said substances or reaction products obtained from said substances. The substances that are to be analyzed are also condensed when the water contained in breathing gas is condensed on a condensation surface. The obtained respiratory condensate is fed directly to the sensors while the condensation surface is functionalized or activated such that an interaction or a chemical reaction takes place with the condensate and/or the substances that are to be analyzed during the condensation process, whereby the signal generated on the sensors is influenced. The invention further relates to a device for recovering respiratory condensates.
