Abstract

Recent advances in instrumentation, principally in the modalities of ionization and mass analysis, have made the mass spectrometer one of the most versatile devices for use in the analytical sciences. The discovery and development of electrospray ionization (ESI) revolutionized mass spectrometry, allowing the ionization of thermally unstable molecules, such as proteins, carbohydrates, inorganic complexes, and glycosylated compounds, which are impossible to analyze by electron ionization. The principal objective of this proposal is the acquisition of a mass spectrometer with ESI to be employed in the analytical science center of the Chemistry Department of the USP Ribeirão Preto School of Philosophy, Science, and Literature, which currently has no equipment of this type. The proposal involves 29 researchers and more than 90 graduate students, at various institutions, working in diverse areas of knowledge, such as organic and inorganic synthesis, chemistry of natural products, materials science, characterization of bioactive secondary metabolites, degradation of drugs and pesticides, and the biotransformation of drugs, as well as affinity and multidimensional chromatography. Because of its analytical versatility, the mass spectrometer requested should meet the basic needs of the various research groups, as well as furthering the understanding of the processes involved, thereby accelerating the research of the groups involved in the proposal and of other groups that might avail themselves of the Analytical Science Center facilities. It should be noted that the Center has the necessary infrastructure for the installation and immediate activation of the equipment requested: 35 m2 of available floor space; a liquid nitrogen station; a high level of technical expertise; and, principally, a professor specializing in analytical methods that require mass spectrometry. These factors ensure that the spectrometer will be maintained in good working order and that the full analytical potential of the equipment will be achieved. (AU)
