Resumen:
|
Commercial breath-alcohol simulators were studied to determine their suitability as calibrating devices and for providing control specimens 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 effluents were measured. The consequences of temperature fluctuations upon effluent-alcohol concentration were determined, as was the number of times a simulator can be used with various breath-alcohol analyzers before reaching 1% alcohol depletion.
