Evaluation of synthesized lipid tethered ligands for surface functionalization of polypropylene capillary-channeled polymer fiber stationary phases.

Capillary-channeled Polymer Fibers as Stationary Phases for Protein Chromatography

The affinity ligand quality of the triazine dye, cibacron blue, toward serum albumin has been well studied [64-68]. By immobilizing the ligand to a stationary phase, affinity separations can be performed in order to remove bulk albumin from serum samples. This decrease in albumin concentration may serve as a direct advantage for proteomics as large amounts of serum albumin hinder the study of l...

High-temperature separations on a polymer-coated fibrous stationary phase in microcolumn liquid chromatography.

Novel polymer-coated fiber-packed microcolumns in liquid chromatography (LC) have been developed. Typical polymeric materials, such as polydimethylsiloxane and polyethyleneglycol, which are conventional stationary phases of capillary columns in gas chromatography (GC), have been employed as coating materials onto the surface of fine filaments. Packed longitudinally with a bundle of polymer-coat...

Investigating the Effect of Various Oxidizing Agents on the Surface Functionalization of Microporous Polypropylene Membranes

Retention behavior on aminoethyl-modified poly(p-phenylene terephthalamide) fiber stationary phases in gas chromatography.

Surface derivatization of Kevlar, poly(p-phenylene terephthalamide), fiber has been studied along with the evaluation of the surface characteristics of the chemically-modified fiber as the stationary phase in packed-capillary gas chromatography (GC). Several experimental parameters in the derivatization reaction have been optimized, and the retention behavior of the surface-derivatized fibrous ...

Effects of Glass-Fiber Reinforced Polymer and Waste Polypropylene Plastic Particles on Geotechnical Properties of Clayey Soils for Using Subgrade in the Pavement

The fine-grained soil including the problematic ones can cause many difficulties in project accomplishment. Settlement and swelling are among the problems of the fine-grained soils. The present study compared the effects of the polypropylene waste plastic (PWP) and glass fiber reinforced polymer (GFRP) on geotechnical properties of the clayey soils for the subgrade design. To this end, the PWP ...
