Enantiomeric Separation by Capillary Electrochromatography on a Sulfated Poly β-Cyclodextrin Modified Silica-based Monolith
Enantiomeric Separation Capillary Electrochromatography Sulfated Poly β-Cyclodextrin
2010/9/17
A sulfated poly β-cyclodextrin (SPCD) modified silica-based monolithic column was prepared for enantiomeric separation. First, 2-hydroxy-3-allyloxy-propyl-β-cyclodextrin (allyl-β-CD) was bonded onto a...

A Fast-Response pH Optode a Fluoroionophore Immobilized Mesoporous Silica Thin Film
2010/9/17
This paper describes the preparation and characterization of an optical pH-sensing device using a H+-responsive fluoroionophore based on boron-dipyrromethene, immobilized to a mesoporous silica thin f...
Structural Analysis of High-Silica Ferrierite with Different Structure-Directing Agents by Solid-State NMR and Ab Initio Calculations
Structural Analysis High-Silica Ferrierite Structure-Directing Agents Solid-State NMR Calculations
2010/9/19
The host-guest interaction in high-silica ferrierite (FER) with different structure-directing agents (SDA), pyridine and piperidine, was analyzed by solid-state 29Si NMR relaxation experiments and mol...
Simultaneous Determinations of Cr(VI) and Cr(III) by Ion-Exclusion/Cation-Exchange Chromatography with an Unmodified Silica-Gel Column
Cr(VI) Cr(III) Ion-Exclusion/Cation-Exchange Chromatography an Unmodified Silica-Gel Column
2010/9/19
In order to characterize the ion-exclusion and cation-exchange properties of an unmodified silica-gel column, the retention behaviors of Cr(VI) and Cr(III) ions were investigated using a Develosil 30-...

Solid-Phase Extractors 8-Aminoquinoline 2-Aminopyridine Covalently Bonded Silica Gel the Selective Separation Calcium
2010/9/20
Two new silica-gel phases were produced directly via the chemical interaction of 3-chloropropyltrimethoxysilane modified silica gel with 8-aminoquioline, phase I and 2-aminopyridine, phase II under re...
Specific Extraction of Sialic-acid-containing Glycans and Glycopeptides Using Serotonin-bonded Silica
Sialic-acid-containing Glycans Glycopeptides Serotonin-bonded Silica
2010/9/17
Serotonin-bonded silica was developed for specific extraction of sialic-acid-containing glycans and glycopeptides. Serotonin, coupled by reductive amination with aldehyde silica particles via its eth...
