The redox reaction that takes place in the test vial. Roadmap to the invention of the breathalyzerâ¢. Breath analyzers use an indirect method of calculating blood alcohol concentration (BAC) based on Henryâs Law, Henryâs Law states that for a closed system at constant temperature and pressure, the concentration of a volatile substance dissolved in a solution is proportional to the concentration of the same substance in the air above the solution, the body as a closed system, then the concentration of alcohol in the air present in a personâs lungs is in proportion to the concentration of alcohol in their blood, Drunkenness caused by alcohol varies from one gender to another, and it is also dependent on body weight, into account while calculating the BAC before charging a person with a DUI, Drunk driving policies and penalties vary from across the globe. endstream endobj 137 0 obj <>stream This training piqued his interest in breath alcohol analyzers.
