GC Measurement of Nitrous Oxide in Exhaled Air
In a note recently published in Clincal Chemistry, researchers describe a method for detection of N2O in exhaled air by using gas chromatography (GC).
In a note recently published in Clincal Chemistry, researchers describe a method for detection of N2O in exhaled air by using gas chromatography (GC). According to the note, nitrous oxide is a relatively stable compound, present at ~310 nL/L in the atmosphere and is produced predominantly by microbial reduction of nitrate. This process, called denitrification, is the conversion of nitrate to gaseous nitrogen compounds, resulting in a product of nitrogen or nitrous oxide under most conditions.

Inside the Laboratory: The Chromatography Laboratory at the University of Rouen
April 18th 2024In this edition of “Inside the Laboratory,” Pascal Cardinael and Valérie Agasse of the University of Rouen in Mont‑Saint-Aignan, France, discuss their laboratory’s work with miniaturizing gas chromatography (GC) columns and systems to improve on-site air analysis of volatile organic compounds (VOCs).
