Dual-Column GC system Measures Coupled N, C and S Stable Isotopes
In an article recently published in Rapid Communications in Mass Spectrometry, researchers developed an application to show that an N, C, and S measurement system allows a three-dimensional view of element dynamics in estuarine systems that are undergoing pollution inputs from upstream watersheds.
In an article recently published in Rapid Communications in Mass Spectrometry, researchers developed an application to show that an N, C, and S measurement system allows a three-dimensional view of element dynamics in estuarine systems that are undergoing pollution inputs from upstream watersheds. Extension of these GC principles should allow coupled H, C, N, and S isotope measurements in future work. The coupled N and C measurements are possible because of a GC separation of N2 and CO2 gases produced in elemental analysis. Adding a second GC column allows additional measurement of sulfur from the same sample, so that combined N, C and S information is obtained routinely.

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).
