Understanding the Science Behind Breath Tests and Their Accuracy
Breath tests are designed to estimate an individual's BAC based on the amount of alcohol present in their breath.

When they exhale, this alcohol can be detected in their breath.
How Breathalyzers Work
Breathalyzers typically employ two main technologies: fuel cell sensors and infrared spectroscopy.

Fuel cell sensors use a chemical reaction to produce an electric current proportional to the amount of alcohol present in the breath sample.
- Electrode Reaction: When a person exhales into the device, alcohol vapors reach an electrolyte solution within the sensor. Alcohol oxidizes at one electrode while reducing at another, generating electricity. Current Measurement: The resulting current is measured and converted into an estimated BAC reading.
2. Infrared Spectroscopy
Infrared technology relies on light DWI lawyer near Lubbock absorption principles.
- Light Absorption: As breath passes through a chamber where infrared light is emitted, alcohol molecules absorb specific wavelengths of light. Concentration Calculation: By measuring how much light is absorbed, the device calculates BAC levels based on known absorption rates of ethanol.
Factors Affecting Breath Test Accuracy
While breath tests are widely utilized, multiple factors can undermine their accuracy:
