title: [An experiment on drinking using breath alcohol monitor (Alcomed 3010) by an electrochemical method].
abstract: A drinking experiment was performed to evaluate the efficiency of a breath alcohol monitor, Alcomed 3010. The ethanol concentrations in blood and breath were determined by gas chromatography, and in particular the breath ethanol concentration was determined with the breath alcohol monitor and by gas chromatography. The results obtained by two methods were compared. Based on the blood and breath ethanol concentrations, the following conclusions were drawn reading the breath alcohol monitor. The monitor has practical merit for determination of the breath ethanol level. It is small, usable anywhere, with little error in determination. In measuring principle, tobacco and acetone did not affected levels with the meter, but methanol, n-propanol and n-butanol affected determinations with the alcohol monitor. The breath (AM)/blood (GC) ethanol ratio was 1:2555. Comparison of the values determined with the alcohol monitor and gas chromatography yielded the equation: y = 0.998 x +/- 0.012 (r = 0.994). When determinations were made on the pure ethanol gas by the meter and gas chromatograph, the equation was: y = 0.974 x +/- 0.021 (r = 0.994). It may be said therefore that the alcohol monitor is both practically and functionally excellent.
