How do fuel cell breathalyzers work
WebHow does Breathalyzer Work? Alcohol that a person drinks shows up in the breath because it gets absorbed from the mouth, throat, stomach and intestines into the bloodstream. As the blood goes through the lungs, some of the alcohol moves across the membranes of the lung’s air sacs into the air because alcohol will evaporate from a solution. WebFeb 15, 2024 · Because alcohol metabolism varies by person, there is no universal way to determine how long a breathalyzer can detect alcohol in a person’s system; however, a breathalyzer can detect alcohol in a person’s system about 15 minutes after consuming alcohol and up to 24 hours later. BAC and standard drinks are used as indicators.
