Exemplars of current commercial breath-alcohol simulators were studied to ascertain their suitability for control tests and as calibrators in breath-alcohol analysis. Temperature, effluent volumes and pressures, effluent-alcohol concentration, and alcohol depletion were measured for simulators coupled with various current alcohol analyzers. Effluent recirculation was found to extend the number of acceptable control test cycles by 3.2 x over nonrecirculation. We found substantial improvements in current commercial simulators and in their performance over those evaluated in 1979.
对当前商用呼气酒精模拟器的样本进行了研究,以确定它们是否适合用于对照测试以及作为呼气酒精分析中的校准器。测量了与各种当前酒精分析仪相连的模拟器的温度、流出物的体积和压力、流出物中的酒精浓度以及酒精消耗情况。发现与非再循环相比,流出物再循环可使可接受的对照测试周期数延长3.2倍。我们发现,当前的商用模拟器及其性能与1979年评估的那些相比有了显著改进。
