Selected ion flow tube mass spectrometry (SIFT-MS) and proton transfer reaction mass spectrometry (PTR-MS) are used to explore ion-molecule reactions in low temperature and pressure plasmas of hexamethyldisiloxane. These techniques shed new light on possible reactions taking place within such plasma environments and validate many of the reaction pathways previously advocated based upon plasma-phase MS. However, SIFT-MS and PTR-MS results draw attention to the possible importance of the H3O+ ion in initiating the formation of oligomeric ions, a point previously missed in plasma-MS studies.
