This research is in the general area of analytical and surface                  chemistry and in the subfield of mass spectrometry. The goal of                 this project is to assess and identify factors which affect the                 sensitivity of matrix-assisted desorption ionization (DI) mass                  spectrometry. The objective is to learn how to tailor matrix                    properties to obtain optimum sensitivity for a given sample.                    Particular emphasis will be placed on understanding the role of                 water as a co-solvent in flow-fast atom bombardment (flow-FAB)                  measurements. The importance of the primary atom beam                           characteristics (flux, mass, and energy) in FAB measurements                    will also be assessed.                                                                                                                                          This research is designed to better understand how the sample                   composition affects the ionization of specific components. This                 information can be used to design specific sample compositions                  which will permit components to be determined at lower                          concentrations.
