This study aims to suggest the partition ratio (Q-factor) of healthy Koreans and the comparison results of breath alcohol concentration(BAC) measurements using two methods (photoacoustic and electrochemical methods) for developing breath alcohol ignition interlockdevices (BAIIDs). Given the relationship between BACs and BrACs and the Q-factor, the alcohol metabolism of healthy Koreans (96males and 91 females) is revealed for understanding the digestion of alcohol and surveying the fundamental data of alcohol-related problems,CO2 concentrations vs. alcohol concentrations, and the performance of alcohol sensors in the marketplace. The average Q-factorof healthy Korean males and females are 1,913 (95% confidence interval from 1,889–1,937) and 1,991 (95% confidence interval from1,945–2,036). Photoacoustic measurements could be applied to predict the BACs of drinkers, which is confirmed by the Bland–Altmanplots presented in this study. The biases based on the partition ratios (Q=1,913 and Q=1,991) in the Bland–Altman plots were -0.0004%(95% CI from –0.0011 to +0.0003% for males) and –0.0017% (95% CI from –0.020 to +0.017% for females).
