What to Do First

Alcohol Breathalyzers

Breath analyzers do not directly measure blood alcohol content or concentration, which requires the analysis of a blood sample. Instead, they estimate BAC indirectly by measuring the amount of alcohol in one's breath. Two Breathalyzer technologies are most prevalent.

Desktop analyzers generally use infrared spectrophotometer technology, electrochemical fuel cell technology, or a combination of the two.

Handheld field testing devices are generally based on electrochemical platinum fuel cell analysis and, depending upon jurisdiction, may be used by police officers in the field as a form of "field sobriety test" commonly called PBT (preliminary breath test) or PAS (preliminary alcohol screening) or as evidential devices in POA (point of arrest) testing.
