Does the Intoxilyzer 8000 use differences in infrared light detected to determine the alcohol concentration?

The Intoxilyzer 8000 employs infrared spectroscopy as its primary method for measuring blood alcohol concentration. It achieves this by directing specific wavelengths of infrared light through a sample of breath. Alcohol molecules absorb particular wavelengths of this infrared light, leading to a measurable difference in the intensity of light detected after passing through the sample. The device quantifies these differences in absorbance to determine the concentration of alcohol in the breath, which correlates to blood alcohol levels.

Therefore, the reason this answer is accurate is based on the fundamental operational principle of the Intoxilyzer 8000, which relies on the detection of infrared light absorption to measure alcohol levels effectively. This approach is distinct from other methods that do not utilize infrared light detection, such as certain blood tests or different types of breath analysis systems that might employ other techniques.
