Normal-phase high performance liquid chromatography of estradiol derivatives on amino- and diol-columns [PDF]
Journal of the Serbian Chemical Society, 2003 The retention behavior of estradiol derivatives was studied by HPLC on chemically bonded polar stationary phases: commercially available amino and diol- columns, as a function of the heptane-propan-1-ol as the mobile phase, when the volume fraction of ...

Automated Image Analysis for Retention Determination in Centrifugal Partition Chromatography
Separations, 2022 In Centrifugal Partition Chromatography, two immiscible liquids are used as mobile and stationary phases. During operation, bleeding of the stationary phase cannot be eliminated completely.

Chemometric Study of Retention on Binary Stationary Phases in Gas Chromatography [PDF]
Journal of Chromatographic Science, 2012 Using gas chromatography, data analysis is performed on a dataset consisting of 486 retention indices, 27 standards (ramified alkanes, aliphatic alcohols, and aromatic compounds), 6 pure and binary stationary phases, and three temperatures. The behavior of the pure stationary phases (OV-3, OV-225, OV-61-OH, and OV-1701-OH) and the binary stationary ...

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.
