STUDIES ON BREATH ALCOHOL ANALYSIS FOR THE ESTIMATION OF BLOOD ALCOHOL LEVELS

With the Kitagawa detector tube method of determining breath alcohol levels, it is stated that there are several problems to be solved. In place of a rubber balloon the authors used a Saran bag which retains alcohol vapor well. The breath alcohol concentration was determined by gas chromatography. The alcohol concentration in rebreathed air correlated well with that of blood. The blood-breath alcohol partition coefficient, from present experiments, was about 2000. There was no significant difference in the alcohol concentration of 3 breath samples (rebreathed air, air expired following breath holding and the second half of air expired following a deep inspiration). A sample size of at least 1500-2000 ml is desirable.
