Apparatus and method for breath analysis and breath gas analyzer

The invention relates to a device (102) for respiratory gas analysis, having a sensor element (108) for detecting at least one analyte in a respiratory gas volume of condensate (310). The sensor element (108) comprises at least one electrode (202) for applying the respiratory gas condensate volume (310) with an electrical potential and / or an electric voltage and a capillary (200) for receiving the respiratory gas condensate volume (310) from a condenser (106) of the device (102), wherein the electrode (202) disposed in an interior region of the capillary (200) or is arranged.
