Infrared Absorption
« Back to Glossary
Definition of Infrared Absorption
Infrared absorption is a method used by the Intoxilyzer 5000 to analyze molecules through infrared spectroscopy and determine the different types of molecules based on the way they absorb infrared light. The Intoxilyzer 5000 is one of the most popular breath testing machines used by law enforcement officers throughout the United States to test driver's BAC levels.
The Intoxilyzer 5000 requires the driver to breathe into the device. Each of the molecules in the driver's breath vibrates and their vibration will change as they absorb infrared light. The Intoxilyzer 5000 will analyze the breath sample to identify ethanol, which absorbs infrared light in different wavelengths from other types of substances. Based on the absorption wavelengths the amount of ethanol present in the sample can be identified.
