An emergency use authorization (EUA) was granted by the U.S. Food and Drug Administration (FDA) for a COVID-19 diagnostic tool that searches for chemical components in breath samples that are linked to SARS-CoV-2 infection.
How Does The Breathalyzer Work?
This new FDA-approved test employs gas chromatography gas mass-spectrometry (GC/MS) to discover compounds in our breath associated with SARS-CoV-2 illness.
GC/MS separates and detects chemical mixtures at the molecular level (the M.S. component). It’s one of the greatest instruments for identifying sample compounds. When a combination is heated, the distinct constituents separate. Heated gases are pushed via a column with inert gas (such as helium).
Mass spectrometry is a trustworthy analytical detector. Once separated, chemicals move into the MS. Mass spectrometry names compounds based on analyte molecule mass.
