Abstract

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.
