Dual-Column GC system Measures Coupled N, C and S Stable Isotopes
August 7, 2007
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.
