1. A system for the detection and analysis of at least one volatile substance in breath samples of a subject comprising:

  • at least one source of infrared radiation adapted to the wavelength range of specific absorption peaks of the substances;

    a plurality of reflecting surfaces of the radiation;

    at least one detector receiving the radiation providing electrical output signals corresponding to the transmission of the radiation within wavelength intervals corresponding to the absorption peaks;

    at least one measuring cell including a mechanical support structure defining the position of the source, the reflecting surfaces and the detector, adapted for the reception and flow of the breath sample, and exposing the breath samples to the radiation;

    at least one electronic signal processing unit with capacity to analyze the signals with respect to pre-programmed information concerning infrared absorption spectra of the substances; and

    a response of the system being displayed or otherwise communicated, and perceived as essentially instantaneous.
