Current Research:

    The majority of my research has gone to utilizing the technique of laser-induced acoustic desorption (LIAD) in a Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometer toward the analysis of non-volatile species.  More specifically, this neutral desorption technique has been coupled with chemical ionization with cyclopentadienyl cobalt radical cation (CpCo+•) for the gas phase analyses of saturated hydrocarbon polymers, such as polyethylene, and others.  Pseudo-molecular weight information is preserved and enables the characterization of the chain-length profile of the neutral parent mixture.

    Another aspect of my research involves gas-phase reactions for deducing specific, protonated functional groups via ion-molecule reactions.  My role in this work has been to implement these reactions that have been developed in an FT-ICR to a QoQ instrument: the Finnigan TSQ 700.
