Ion Exchange Resin Analysis by using Pyrolysis-GCxGC-MS
MSTips No. 274
Recently, we developed a new gas chromatography/high resolution time-of-flight mass spectrometer (GC/HR-TOFMS) system which allows using multiple ionization techniques not only electron ionization (EI) but also field ionization (FI) and photo ionization (PI). PI is a soft ionization technique that provides high sensitivity and molecular ion information for compounds with ionization energies below the maximum practical photon energy (10.8 eV) of the deuterium lamp used in our current design.
In this study, pyrolysis (Py)/GCxGC/HR-TOFMS system was applied to investigate the pyrolysis products of Vinylpyridine and Divinylbenzene copolymer as the ion exchange resin sample.
