The Intoxilyzer 5000 is the device law enforcement uses in Georgia to detect alcohol in a suspected drunk drivers' breath. What most people do not know is that this device does not really measure alcohol. It actually uses infrared light beams which are absorbed by chemical compounds, including alcohol in the breath which contains the "methyl group" in its molecular structure. The more absorption one has, the higher the blood alcohol reading. The machine is set to just "assume" that the compound is likely alcohol. Surprisingly thousands of compounds can register as alcohol, with one of those being acetone.
