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.
进行了一项饮酒实验，以评估呼气酒精监测仪Alcomed 3010的效能。通过气相色谱法测定血液和呼气中的乙醇浓度，特别是使用呼气酒精监测仪并通过气相色谱法测定呼气乙醇浓度。比较了两种方法获得的结果。根据血液和呼气乙醇浓度，读取呼气酒精监测仪得出以下结论。该监测仪在测定呼气乙醇水平方面具有实际价值。它体积小，可在任何地方使用，测定误差小。在测量原理上，烟草和丙酮不会影响该仪器的测定结果，但甲醇、正丙醇和正丁醇会影响酒精监测仪的测定。呼气（AM）/血液（GC）乙醇比率为1:2555。比较用酒精监测仪和气相色谱法测定的值，得出方程：y = 0.998x ± 0.012（r = 0.994）。当用该仪器和气相色谱仪对纯乙醇气体进行测定时，方程为：y = 0.974x ± 0.021（r = 0.994）。因此，可以说该酒精监测仪在实际应用和功能方面都非常出色。
