Characterization of stationary phases by retention data and solvation parameters
Journal of Separation Science, 2001Method requirements for the characterization of stationary phases are established. The completeness of the method and the influence of a mixed retention mechanism involving both solvation and adsorption on characteristic phase parameters are discussed.

Influence of structure of alkenes on their retention on different stationary phases
Chromatographia, 1988Retention indices of different alkenes are correlated with connectivity and topological parameters. The appropriate statistically valid relations hips are derived and discussed.

Cellulose and cellulose mono-, di-, and triacetate were used as stationary phases for liquid chromatography with water as a mobile phase, and the retention behavior of alcohols, ethers, ketones, and chlorides was examined. For cellulose acetate columns, the logarithm of the specific retention volume, (logV g *

Journal of chromatography, 1994
We provide a somewhat historical perspective on the work that has been accomplished that supports the suggestion of phase transitions in reversed-phase liquid chromatographic bonded phases. In addition to this general review, we consider from both a practical and theoretical viewpoint the implications of such transitions in the rational design of ...

The partitioning model of retention for reversed-phase liquid chromatography, described by mean-field statistical thermodynamic theory, asserts that one principal driving force for solute retention is the creation of a solute-sized cavity in the stationary phase. Beyond a critical stationary phase bonding density, increased grafted chain density should

The retention mechanism in reversed-phase liquid chromatography (RPLC) has been investigated by examining the temperature dependence of retention, with emphasis on the role of the stationary phase in the retention process. Both chromatographic temperature studies and differential scanning calorimetry were used to examine the role of alkyl chain bonding

Furocoumarins are natural chemicals produced by plants of several families which are used in various fields of pharmacology. Their preparative isolation and separation represents a challenge due to considerable natural diversity and, simultaneously, structural proximity.

Overview of the retention in subcritical fluid chromatography with varied polarity stationary phases
Journal of Separation Science, 2008AbstractRetention and separation of achiral compounds in supercritical fluid chromatography (SFC) depend on numerous parameters: some of these parameters are identical to those encountered in HPLC, such as the mobile phase polarity, while others are specific to SFC, as the density changes of the fluid, due to temperature and/or pressure variations ...
