Breathalyzer Defense Lawyer
DUI Attorneys Defending Clients in Ann Arbor, Detroit, Grand Rapids, Lansing, and Throughout Michigan Accused of DUI and OWI
Chemical breath tests are frequently used when an individual is suspected of DUI/OWI to establish BAC, or blood alcohol content. Datamaster breath tests are often administered at the police station after a roadside preliminary breathalyzer test has been given to establish a BAC reading which may be more accurate. The Datamaster measures breath alcohol using an infrared light beam, which is absorbed by ethanol, the scientific name for alcohol. However, any equipment used to measure alcohol in the breath may be faulty, which can ultimately mean flawed test results.
As highly regarded Michigan DUI attorneys, we know that individuals are often convicted based primarily on the results of these breath tests. It is imperative you consult with a capable lawyer when accused of DUI, OWI, or any drunk driving offense so that your legal rights and freedom are protected.

Michigan DUI and Datamaster Breath Test
Essentially, BAC or blood alcohol content from an individual's sample may be measured using the Datamaster breath test, which works via infrared spectrophotometry. While it may sound a bit complicated, it's actually quite simple. When someone breathes into the device, ethanol (alcohol) molecules vibrate in the chamber of the device. These molecules absorb the infrared energy. The Datamaster device determines the amount of energy that passes through the chamber by taking a sample of the amount of energy combined with the individual's breath at the end of the device. This energy is affected by the content or concentration of alcohol in the blood.
Potential Problems with Datamaster Breath Tests
Results of a Datamaster breath tests may be faulty due to a number of factors, one of which is the fact that infrared light cannot distinguish between ethanol and other molecular chemicals such as acetone, which are highly similar in structure. Acetone may be found in the breath of individuals who are diabetics, are on the Atkins diet, and for other reasons. Many molecular chemicals may have the same basic structure as ethanol, which can result in inaccurate BAC readings.
All breath tests may be affected by various foods or substances, which may be in an individual's mouth, such as residue of acidic foods, mouthwash, jewelry, or alcohol residue. Medical conditions such as respiratory disorders or acid reflux and other gastro-intestinal or esophageal disorders may impact results.
Additionally, the police officer who administers the test should be qualified and properly trained. The actual device should be tested on a regular basis frequently as well to ensure it is functioning properly. Despite all of the flaws and potential inaccurate results, the Datamaster breath test is used in court to provide evidence of an individual's BAC.
