Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]
Despite the wide range of HPLC stationary phases available for reversed-phase high-performance liquid chromatography (RP-HPLC) and the in-depth studies using probes to highlight differences between them, there is very little in the way of stationary ...

Application of Natural and Modified Biomacromolecules in Miniaturised Separative Analytical Techniques [PDF]
In pharmaceutical R & D, drug stereochemistry, and consequently the rotation of enantiomers, is very important. Because they act as chiral selectors in vivo, biomacromolecules have been extensively used as chiral selectors for the liquid chromatographic (

Electrochromatographic retention of peptides on strong cation‐exchange stationary phases [PDF]
ELECTROPHORESIS, 2010 AbstractWe analyze the systematic and substantial electrical field‐dependence of electrochromatographic retention for four counterionic peptides ([Met5]enkephalin, oxytocin, [Arg8]vasopressin, and luteinizing hormone releasing hormone (LHRH) ) on a strong cation‐exchange (SCX) stationary phase.

Normal and reversed phase high performance liquid chromatography of some new 1, 2, 4-triazole derivatives [PDF]
Acta Periodica Technologica, 2003 The retention behaviour and separation ability of normal and reversed phase HPLC with one non-polar and two polar mobile phases, have been studied by measuring the retention constants of a series of newly synthesized 1,2,4-triazole derivatives.

Retention of Anions on Silica-based Metalloporphyrin Stationary Phases
Analytical Sciences, 2002 The silica-based Fe(III)-protoporphyrin and Zn-tetraphenylporphyrin stationary phases were examined for the HPLC separation of anions. The retention of nine common inorganic anions as well as benzoate anion (BA) and its hydroxy analogues (HBA) was examined using tartrate, acetate, and succinate eluents.

Retention of Halogenated Solutes on Stationary Phases Containing Heavy Atoms [PDF]
Molecules, 2013 To examine the effects of weak intermolecular interactions on solid-phase extraction (SPE) and chromatographic separation, we synthesized some novel stationary phases with a heavy atom effect layer by immobilizing halogenated aromatic rings and hydroxyl groups onto the surface of a hydrophilic base polymer.

Separation and lipophilicity of some new steroid derivatives in normal- and reversed-phase high performance liquid chromatography [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2011 The separation ability and retention of normal and reversed phase HPLC with, respectively, three non-polar and two polar mobile phases, have been studied by measuring the retention constants of a series of newly synthesized estrone derivatives.
