Abstract: A system for breath analysis includes a breath sampling apparatus for collecting substances from the exhalation breath of a test subject; and a sample preparation apparatus for extracting selected analytes. The method includes: placing a sampling disc in the proximity of exhalation openings of a test person; receiving exhalation breath on the sampling disc for a predetermined period of for example about 1 hour; collecting a sample of substances from the exhalation breath by adsorption on the sampling disc corresponding to the average amount and composition of substances exhaled during a length of time; placing the sampling disc with the collected substances in a desorption vessel; releasing the collected substances from the sampling disc in the desorption vessel by heating in an inert atmosphere; preparing the sample by adsorption of selected analytes among the sample of substances; and analyzing selected analytes by gas chromatography.
