A novel "Correlated Ion and Neutral Time Of Flight" Method: event-by-event detection of neutral and charged fragments in Collision Induced Dissociation (CID) of mass selected ions

Abstract

A new mass spectrometric MS-MS method based on Time Of Fight measurements performed on an event-by-event detection technique is presented. This "COrrelated Ion and Neutral Time of Flight (COINTOF)" method allows to explore CID fragmentation processes by directly identifying not only all ions and neutral fragments produced but also their arrival time correlations within each single fragmentation event from a dissociating molecular ion. This constitutes a new step in the characterization of molecular ions. The method will be illustrated here for a prototypical case involving Collision Induced Dissociation (CID) of protonated water clusters H+(H2O)n=1-5 upon collisions with argon atoms.
