During a drinking experiment 12 persons were tested with two different breath-alcohol analysers. Both instruments fulfill essential requirements according to the expertise of the Federal Health Office concerning the forensic applicability of breath analysers. One instrument was equipped with different measuring systems (infrared system and fuel cell). The other instrument had only an infrared system and in each case two measurements were performed with this system. With both instruments breath temperature and breath volume were determined, so that the BrAC values could be compared after they were related to the reference temperature of 34 degrees C. Taking into consideration the course of BrAC as a function of time a measuring precision of all systems was found which can be characterized by a standard deviation of less than 0.01 mg/l.
在一项饮酒实验中，使用两种不同的呼气酒精分析仪对12人进行了测试。根据联邦卫生局关于呼气分析仪法医适用性的专业知识，这两种仪器均满足基本要求。其中一台仪器配备了不同的测量系统（红外系统和燃料电池）。另一台仪器仅配备红外系统，并且在每种情况下都使用该系统进行两次测量。使用这两种仪器测定了呼气温度和呼气量，以便在将呼气酒精浓度（BrAC）值与34摄氏度的参考温度相关联后进行比较。考虑到BrAC随时间的变化过程，发现所有系统的测量精度均可用小于0.01 mg/l的标准差来表征。
