Gas Chromatography and Mass Spectrometry: The Technique

Nonthermal Plasma-Stimulated C–N Coupling from CH4 and N2 Depends on the Presence of Surface CHx and Plasma-Phase CN Species

“…GC−MS is a common analytical technique for analyzing volatile organic compounds (VOCs) rather than nonvolatile organic com- pounds. 59 In this work, the analysis of C−N coupled species using GC-MS was performed ex situ. Thus, it is possible that if only a fraction of C−N coupled species formed on the metal surfaces is composed of volatile C−N coupled species, it would not be detected by using ex situ GC−MS analysis.…”

“…Similarly, Ruiz-Bermejo et al analyzed tholins using both solid-phase microextraction (SPME) followed by GC–MS and conventional GC–MS for the detection of polycyclic aromatic hydrocarbons (PAHs), but PAHs were not detected using SPME/GC–MS and GC–MS.
