Roadside Breath Test for Drugs Could Be on Horizon
Date:4/26/2013

y certain substances picked up from the fluid lining the airway, according to the news release. Any compound that has been inhaled or is present in the body can contaminate this fluid and pass into the breath, where it can be detected.

In this study, the researchers used a Swedish-made device called SensAbues, which consists of a mouthpiece and a micro-particle filter. When a person breathes into the mouthpiece, saliva and large particles are separated from the micro-particles that need to be measured.

The micro-particles are deposited on a filter, which can then be sealed and stored until analysis is conducted using lab tests known as liquid chromatography and mass spectrometry.
