Mirela-Adelaida Anghel, Fanel Iacobescu, Alexandru Salceanu
Abstract:
Breath alcohol analyzers are widely accepted as legal measurement 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; calculation of Zeta score and Trueness test - En numbers, both for simulator system and CRMs; 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.
