Arizona Breath Tests
There exist three major types of breath testing devices. Each device has a mouthpiece, a tube through which the suspect blows air, and a sample chamber where the air goes. Talk to your az dui lawyer to help you understand how these devices are notoriously inaccurate.
Breathalyzer
This type of breath testing device uses a chemical reaction involving alcohol that produces a color change. A suspect breathes into the device and the breath sample is bubbled in one vial through a mixture of sulfuric acid, potassium dichromate, silver nitrate and water.
Intoxilyzer
This type of devise detects alcohol by infrared (IR) spectroscopy. The intoxilyzer uses infrared spectroscopy. The spectroscopy identifies molecules based on the way they absorb infrared light and calculates the BAC based on the absorption of infrared light.
Alcosensor III or IV
This type of devise detects a chemical reaction of alcohol in a fuel cell. These devises use fuel cells. Court cases can turn on the Intoxilyzer 5000 Weaknesses.
