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.
