| Abstract Scope |
This work focuses on the development of a new, rapid analytical technique for addressing surface contamination and headspace analysis. With materials compatibility and aging studies in mind, techniques such as gas-chromatography/mass spectrometry (GC-MS) are often used to look at highly volatile species in the headspace of a closed system. However, these techniques can under-represent semi-volatile species that often spend more time interacting with the surfaces, and thus can pose a serious threat from a compatibility standpoint. Further, these species are often volatile or reactive enough that removing a surface for external analysis will compromise results. We have developed a technique that uses porous materials to concentrate and stabilize such species, permitting ex-situ techniques to be applied, primarily desorption electrospray ionization-mass spectrometry (DESI-MS).
