Mass spectrometric study of low energy Cs ion-induced sputtered fragmentation of PADC polymer.

In this study, low-energy cesium (Cs ) ion-induced sputtered fragmentation of poly allyl diglycol carbonate (PADC) was investigated using mass spectrometry. The collision-induced dissociation mechanism revealed emission of various fragments, including monoatomic (H , C , O ), diatomic (C ), and multiatomic (C , CO , C O , C O ) species within the Cs ion energy range of 1-5 keV. The anion current of these fragments exhibited a linear increase with rising incident Cs ion energy, indicating a corresponding rise in fragment abundance.
