What is the minimum volume of breath needed for an accurate sample on the Intoxilyzer 9000?

The correct answer regarding the minimum volume of breath needed for an accurate sample on the Intoxilyzer 9000 is 1.5 liters. This requirement is crucial because the Intoxilyzer 9000 is designed to analyze a sufficient volume of breath to ensure the accuracy of blood alcohol concentration (BAC) readings.

When the device collects a breath sample, it needs a specific amount of air to ensure that the results are reliable and representational of an individual’s BAC. The technology behind the Intoxilyzer relies on infrared spectroscopy, which requires adequate breath volume to detect alcohol content accurately.

Using a volume smaller than 1.5 liters may lead to insufficient alcohol detection and potentially skewed results. This is why the protocol emphasizes the need for a minimum breath volume that meets or exceeds this threshold — to minimize the chances of false negatives or inaccuracies in the reporting of BAC levels.
