TLDR
The solvation parameter model for the 200 degrees C processed F-LTGC showed similar trends in the relative importance of intermolecular interactions as previously found for octadecyl-polysiloxane stationary phases, while the 400 degrees C process had similar intermolescular interactions with solutes as found with porous glassy carbon in that pi-pi interactions with the carbon surface contribute more so to the retention.About:

Solubility of pharmaceutical compounds in supercritical carbon dioxide
TL;DR: In this article, an activity coefficient model based on linear solvation energy relationships was proposed to estimate the solubility behavior of pharmaceutical compounds in supercritical fluids, and the parameters of this model were further generalized as a function of the properties of the pharmaceutical compounds.

Separation-Oriented Derivatization of Native Fluorescent Compounds through Fluorous Labeling Followed by Liquid Chromatography with Fluorous-Phase
TL;DR: Experimental results indicate that thefluorous-phase column can selectively retain fluorous compounds including fluorous-labeled analytes on the basis of fluorous separation, the first step toward the introduction of fluored derivatization in quantitative LC analysis.

The use of characteristic volumes to measure cavity terms in reversed phase liquid chromatography
Michael H. Abraham,J. C. McGowan +1 more
TL;DR: In this paper, it was shown that the use of the McGowans characteristic volume, Vx, is equivalent to using Leahy's computer-calculated intrinsic volumes, V1, for the cavity term mV/100, for 209 gaseous, liquid, and solid solutes.

Hydrogen bonding. 32. An analysis of water-octanol and water-alkane partitioning and the Δlog p parameter of seiler
TL;DR: A general linear solvation energy equation has been used to analyze published partition coefficients in the systems water-octanol, water-hexadecane), water-alkane, and water-cyclohexane and shows that solute hydrogen-bond basicity, dipolarity/polarizability and size are significant factors that influence the delta log P parameter.
