Synthesis And Evaluation Of Novel Silica Hydride-Based Stationary Phases For Bioanalytical Application, Seiichiro Watanabe May 2019

Synthesis And Evaluation Of Novel Silica Hydride-Based Stationary Phases For Bioanalytical Application, Seiichiro Watanabe

Most HPLC columns are packed with silanol-rich (Si-OH) type-B silica material that often participates in undesired electrostatic interactions with the analyte solutes and produces poor peak shape [1,2]. These silanols are also known to facilitate surface hydration necessary for HILIC retention mode for polar analyte molecules. However, the hydrated surface composition can easily fluctuate, and thus results in a poor reproducibility and requires lengthy equilibration step. In this study, four novel stationary phases have been developed by using the TYPE-CTM Silica Hydride material, which has replaced up to 95% of the surface silanols with silicon-hydride (Si-H) groups. One of the …

Librarians from Utah State University explain recent efforts to encourage subject librarians to take a more holistic view of their roles. We are shifting from a traditional emphasis primarily on collection development and refocusing on natural connections between collections, instruction, liaison, and reference service. The poster provides background about Utah State University’s situation and explains our approach to analyzing local needs and culture to inform development of a new organizational structure. We describe our vision of subject librarianship, the process by which we assessed librarians’ ideas and goals for performing as subject librarians, and the actions we are taking to …
