BAC (Blood alcohol Concentration) can be analysed by breath analysis from the alcohol breathing from the aveoli in the lungs because alcohol is absorbed in the blood stream and does not break down easily as it is volatile. 2100 ml of alveoli air contains 1 ml of alcohol. This ratio of 2100:1 determines the amount of alcohol through a breath analyser that was invented by Dr Robert Borkenstein for the Indiana State Police in 1954.
1. The breath analyser has vials through which alcohol breath passes through mixture of sulfuric acid,postassium dichromate(reddish -orange color),silver nitrate (catalyst) and water to react to chromiun sulphate (green) + potassium sulphate + acetic acid + water.The change in color due to reaction is analysed through a photocell that gives current output and shown in milliamp meter needle deflection.
2. The second type uses infrared (IR) spectrograph for the current to be fed in a microprocessor to determine the alcohol content in the breath.
3. Alcosensor uses fuel cell technology in which porus acid electrolyte is sandwiched between two platinum electrodes that react with alcohol breath to produce platinum oxide,protons & electrons that is analysed through a microprocessor

No. Blood alcohol level is a measure of how much alcohol is in solution in the blood. It is possible to affect the rate of absorption, but not the level that is reached.
What percentage of alcohol in the body's blood determines intoxication if given a Breathalyzer test?
A blood alcohol concentration (BAC) of 0.08% is the legal limit for intoxication in most states when measuring with a Breathalyzer test. This level correlates with impaired judgment, coordination, and reaction time.
What is alcohol test?
An alcohol test is a method used to measure the presence of alcohol in a person's body. Common tests include breathalyzer tests, blood tests, and urine tests, which can determine a person's blood alcohol concentration (BAC) level. These tests are often used by law enforcement to assess if someone is driving under the influence of alcohol.
What are the functions of a breathalyzer?
A breathalyzer detects the amount of liquor in the test taker's system. It is used by police to see if a suspect had more than the legal amount in their system while operating a motor vehicle. It's used in conjunction with other field sobriety tests. The body does not digest alcohol; it absorbs it into the bloodstream. The alcohol does not mix into the blood, but rather says intact. As the blood passes through the lungs, the alcohol is released through breathing. A breathalyzer measures the amount of alcohol. The alcohol present in 2,100 ml of expelled breath is exactly equivalent to the amount of alcohol in 1 ml of blood. This measurement makes it possible measure the driver's level of intoxication, based on the figures set for legal limits.
Can being tazered effect a breathalyzer test?
No, not a chance. A breathalyzer measures only the level of alcohol contained in ones exhaled breath.
How is blood alcohol determined?
Level of intoxication and, for legal purposes, whether or not an individual is capable of driving or performing other tasks safely.
