IN VITRO ACCURACY AND PRECISION STUDIES COMPARING DIRECT AND DELAYED ANALYSIS OF THE ETHANOL CONTENT OF VAPOR

In vitro accuracy and precision studies were conducted using silica gel, magnesium perchlorate, and indium encapsulation breath collection tubes in conjunction with three infrared breath ethanol analyzers (BAC Verifier, Intoxilyzer 5000, and Intoximeter 3000), the Breathalyzer 900A, and the GC Mark IV. Statistical analyses revealed good accuracy and precision and correlation between direct and delayed vapor ethanol analyses for each combination of instruments and collection devices (range=0.000 to 0.250g/210L, N=42/instrument, r greater than 0.00). Delayed vapor ethanol analysis utilizing each instrument and collection device combination appears to predict satisfactorily the original vapor ethanol concentrations.
