Development Of Inlet And Vacuum Ionization Methods For Characterization Of Biological Materials By Mass Spectrometry, Beixi Wang

Wayne State University Dissertations

Inlet ionization and vacuum ionization are novel ionization methods to produce electrospray ionization (ESI)-like ions from the solid or liquid states, operating from atmospheric pressure (AP) or vacuum, without the use of voltage or the necessity of high energy input such as a laser or particle beam. The fundamental aspects were probed for better understanding of the novel ionization processes. Initial applications were attempted to utilize the novel ionization methods for fast, robust, and quantitative analyses.

For inlet ionizations (laserspray ionization inlet, LSII; matrix assisted ionization inlet, MAII; and solvent assisted ionization inlet, SAII), small (e.g. drugs) to large (e.g. …
