Ultrathin-layer Chromatography Using an Electrospun Polyacrylonitrile Stationary Phase

Abstract

Polyacrylonitrile electrospun nanofiber are fabricated by electrospining process to transfer to use as ultrathin-layer chromatography stationary phase. The separation of 5 water soluble food dyes were studied on the novel polyacrylonitrile layers. Low volumes of analyte and mobile phase solution were needed. As ultrathin stationary phase, such layers are suited for its integration into the Office Chromatography concept. In this project, the electrospun polyacrylonitrile nanofibrous will be used as stationary phase for studying the separation of water soluble food dyes. The effect of morphology of fibers on separation activities would be investigated. Finally, the comparison results of separation efficiency between polyacrylonitrile and commercial stationary phase would be analyzed.
