ALCOHOL BREATH ANALYSER :
Alcohol consumption is a prevalent social activity worldwide, with millions of people indulging in it regularly. However, excessive alcohol consumption can lead to impaired judgment, impaired driving, and several other health issues. To tackle this problem, breathalyzers or alcohol breath analyzers have become an essential tool for law enforcement and medical professionals. In this blog post, we'll explore the concept of alcohol breath analyzers and their significance.
What is an Alcohol Breath Analyser?
An alcohol breath analyser is a handheld device that measures the amount of alcohol in a person's breath. The device works on the principle of infrared spectroscopy or electrochemical fuel cell technology. When a person exhales into the device, the alcohol in their breath reacts with the sensor in the device, and the sensor produces an electrical current or a light signal, which is proportional to the alcohol concentration.
Why are Alcohol Breath Analyzers Used?
Alcohol breath analyzers are primarily used to measure blood alcohol concentration (BAC) in individuals. This is important in various settings, including law enforcement, workplace safety, and medical practice.
Law Enforcement: The use of alcohol breath analyzers is a common practice in law enforcement, especially in traffic control. The device is used to detect drivers who are driving under the influence of alcohol. In most countries, the legal limit for BAC while driving is 0.08%. Drivers who exceed this limit are considered to be driving under the influence (DUI) and are subject to penalties.
Workplace Safety: Alcohol breath analyzers are also used in workplaces to ensure that employees are not under the influence of alcohol while on the job. This is especially important in industries such as construction, transportation, and manufacturing, where employees operate heavy machinery and equipment.
Medical Practice: Alcohol breath analyzers are also used in medical practice to monitor patients with alcohol use disorders. The device helps medical professionals to determine the level of alcohol in a patient's system, which is essential for prescribing appropriate treatment.
Types of Alcohol Breath Analyzers
There are two main types of alcohol breath analyzers: infrared spectroscopy and electrochemical fuel cell technology.
Infrared Spectroscopy: Infrared spectroscopy is the most commonly used method in alcohol breath analyzers. The device measures the amount of alcohol in a person's breath by passing infrared light through a sample of the breath. The light is absorbed by the alcohol molecules in the breath, and the amount of absorption is proportional to the alcohol concentration.
Electrochemical Fuel Cell Technology: Electrochemical fuel cell technology is another method used in alcohol breath analyzers. This method involves passing the breath sample through a fuel cell that oxidizes the alcohol, producing an electrical current. The current is proportional to the alcohol concentration.
Advantages of Alcohol Breath Analyzers
Quick and Accurate: Alcohol breath analyzers provide quick and accurate results. The test takes only a few seconds to complete, and the results are available immediately.
Non-invasive: Alcohol breath analyzers are non-invasive, which means that they do not require blood samples or other invasive procedures.
Easy to Use: Alcohol breath analyzers are easy to use, even for individuals who are not trained in their operation.
Portable: Alcohol breath analyzers are small and portable, which makes them convenient for use in various settings.
Cost-effective: Alcohol breath analyzers are relatively inexpensive, making them an affordable option for law enforcement agencies, medical professionals, and workplaces.
Limitations of Alcohol Breath Analyzers
Environmental Factors: Environmental factors such as humidity, temperature, and altitude can affect the accuracy of alcohol breath analyzers.
Mouth Alcohol: Mouth alcohol, which is alcohol that remains in the mouth after consuming alcoholic beverages, can cause false readings in alcohol breath analyer.
