Released on April 23, 2013, the device was the first smartphone-connected breathalyzer available for commercial purchase. [7] The accuracy of BACtrack Mobile was independently tested and found to be comparable to law enforcement breath alcohol testers. [8] The results of one such study were published in the Journal of Injury Prevention. [8]
In early testing, the experimental breathalyzer design provided results with high accuracy in about a minute. It functions by collecting a breath sample and directing it towards an electrochemical biosensor coated with antibodies specific to the SARS-CoV-2 virus. If the virus is present, the sensor produces a signal, indicating a positive test.
This current is then measured and converted to an alcohol equivalent reading. Although fuel cell technology is not as accurate or reliable as infrared spectroscopy technology used in evidentiary breathalyzers, they are cheaper and tend to be more specific for alcohol. Alcohol, as defined here, includes isopropanol, sorbitol, menthol, methanol ...

A breathalyzer or breathalyser (a portmanteau of breath and analyzer/analyser), also called an alcohol meter, is a device for measuring breath alcohol content (BrAC). It is commonly utilized by law enforcement officers whenever they initiate traffic stops .
The Breathometer was a small device that plugged into the audio jack of a smartphone, coupled with a dedicated app that reads the user's blood alcohol content (BAC). [8] [19] [20] [9] The app utilized the smartphone to provide the processing power, which allowed the device to be small enough to fit on a standard keychain.
Breathalyzer – by far the most common usage of this term relates to the legal breath test to determine if a person is driving under the influence of alcohol. Hydrogen breath test – it is becoming more and more common for people to undertake a medical test for clinical diagnosis of dietary disabilities such as fructose intolerance , fructose ...
Breath analysis can be done with various forms of mass spectrometry, but there are also simpler methods for specific purposes, such as the Halimeter and the breathalyzer. Gas chromatography-mass spectrometry GC-MS; Gas chromatography-UV spectrometry GC-UV; Proton transfer reaction mass spectrometry PTR-MS and PTR-TOF
