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.
Résumé
Ethylomètres sont largement acceptées comme des instruments de mesure légales utilisées pour la détermination de la concentration massique d’alcool dans l’air expiré. Le document met l’accent sur les points suivants: configuration du système expérimental; l’assurance de la traç;abilité des étalons; l’influence de CO2 et l’influence de la température de l’air expiré lorsque la température du corps humain augmente jusqu’à 38, 39 ou, dans des conditions extrêmes, jusqu’à 40 °C..
