چکیده
I f e e l some diffidence in talking to this assembly because I have only been in this field for two years, whereas there are a number of people here who have had many years of experience and knowledge of the subject. The only excuse I can put forward is that I have had the great benefit of their experience as recorded in the literature, and some benefit from being able to bring a fresh eye to the subject.

Table 2 . End - Expiratory Breath Temperatures in Human
We studied several relevant biological aspects of breath-alcohol, analysis in 55 healthy men and women, after alcohol ingestion and during breathalcohol analysis with a typical 4th-generation instrument. We measured breath volumes, delivery pressures, and end-expiratory temperatures, with the following findings: End-expiratory temperature, 32.4135.69 #{176}C (mean, 34.53 #{176}C); forced vital ...

متن کاملBreath-Alcohol Simulators: Scientific Basis and Actual Performance
Commercial breath-alcohol simulators were studied to determine their suitability as calibrating devices and for providing control spocimens in breath-alcohol analysis. The best-fit exponential equation for the air/water partition of ethanol was found to by y = 0.0145e 0.06583x, where x = temperature ~ and y = Ka/wxl03. Temperature, volume, pressure, and alcohol depletion of simulators and their...
