How many wavelengths of light does the Intoxilyzer 8000 use to analyze a sample?

The Intoxilyzer 8000 utilizes two specific wavelengths of light to analyze a breath sample for the presence of ethanol. This dual-wavelength approach allows the device to differentiate between ethanol and other substances that may also be present in the breath. By employing two wavelengths, the instrument can apply a more accurate measurement technique, enhancing its ability to ascertain the blood alcohol concentration (BAC) while minimizing interference from non-alcoholic compounds. This method is critical to providing reliable results in breath alcohol testing, making the two wavelengths a fundamental aspect of how the Intoxilyzer 8000 operates.
