While it’s easy enough to create bad breath in your own mouth - sleeping with your mouth open or taking a swig of alcohol can do the trick - it is more difficult to do it in a laboratory. Germany’s National Institute for Physical and Technical Sciences, however, has got it down to an art form, creating bad breath in the lab as a way to more accurately test breathalyzers.
Called the Physikalisch-Technische Bundesanstalt (PTB), the institute reports creating synthetic alcoholic breath in order to calibrate devices that test the breath for blood alcohol content (BAC). Their latest innovation in artificial bad breath allows it to be made to very specific BACs.
To do so, researchers at the PTB use mass flow controllers to determine the exact rate that ethanol and water are added to air to form a pungent, artificial alcohol breath.
The new technology, the PTB says, will allow German breathalyzers to even more accurately detect spiked eggnog on drivers’ breath this Christmas.
To avoid alcohol breath over the holiday, first and foremost, do not drink and drive. After safe drinking, brushing your teeth twice a day and rinsing your mouth with specialty breath fresheners may eliminate the odor molecules associated with bad breath.
