ABSTRACT Calibrating and testing forensic breath test instruments using wet-bath simulators heated to 34°C is fundamentally dependent on the assumed air/water partition coefficient for ethanol employed. Models developed from the early experimental work of Harger et al. (1950), defining the partition coefficient as a function of temperature, have formed the basis for many calibration and testing protocols. However, it appears these models may have been developed from the inappropriate fitting of… Expand
