CHEMISTRY Departmental Seminar M.S. Final Seminar Ms. Kavita Prajapati San José State University Adviser: Dr. Joseph Pesek Synthesis and Characterization of Silica Hydride Based Flourinated Stationary Phases Alkyl- and phenyl- based fluorinated bonded phases have shown enhanced selectivity with altered elution orders for molecules differing in hydrophobicity and hydrophilicity in comparison with C8 and C18 reversed phase columns. Two fluorinated bonded phases have been synthesized using a hydrosilation procedure. Bonded moieties have been characterized by elemental and spectral analysis. Aqueous normal phase (ANP) chromatography has similar retention behavior as normal
