THE INFLUENCE OF TEMPERATURE AND CO2 IN EXHALED BREATH L'INFLUENCE DE LA TEMPÉRATURE ET DE CO2 DANS L'AIR EXPIRÉ

Breath alcohol analyzers are widely accepted as legal measuring instruments used for determination of the mass concentration of alcohol in exhaled breath. The paper focuses on the following issues: configuration of experimental system; the assurance of traceability at the highest standards; the influence of CO2 and on the influence of the exhaled breath temperature when the human body's temperature increases up to 38, 39 or, in extreme conditions, up to 40 °C.
