Liquid chromatographic retention studies using polystyrene-divinylbenzene stationary phases in reversed-phase and normal-phase eluents

Abstract

This manuscript has been rqsroduced from the microfilm master. UMI films the text directly fiom the ori^nal or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be fi'om any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikdy event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize nuiterials (e.g., m^s, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photognq)hed in one exposure and is included in reduced form at the back of the book.

Development and Application of a Novel SPE-Method for Bioassay-Guided Fractionation of Marine Extracts

“…Independently of the efficiency, this procedure can be highly time consuming, solvent demanding, poorly reproducible and expensive. Since the pioneering applications in early 80s, materials based on poly(styrene-divinylbenzene) (PS-DVB) have been largely used as chromatographic support for fractionation and purification of organic components from complex matrices [ 7 , 8 , 9 ]. In particular, PS-DVB resin is an attractive adsorbent for extraction of various types of organic compounds due to pH stability and the hydrophobic surfaces that highly retain non-polar molecules.…”
