Journal ArticleDOI
Determination of solute lipophilicity, as log P(octanol) and log P(alkane) using poly(styrene–divinylbenzene) and immobilised artificial membrane stationary phases in reversed-phase high-performance liquid chromatography
Michael H. Abraham,Harpreet S. Chadha,Ruben A.E Leitao,Robert C. Mitchell,William J. Lambert,Roman Kaliszan,Antoni Nasal,P. Haber +7 more
TL;DR: In this paper, the linear free energy relationship (LFE) was used to characterize RP-HPLC systems with poly(styrene-divinylbenzene) phases, as log Palk or log Pcyc, where the latter is the water cyclohexane partition coefficient.
Journal ArticleDOI
Lipophilicity and pKa estimates from gradient high-performance liquid chromatography.
TL;DR: The linear-solvent strength (LSS) model of gradient elution has been applied to estimate parameters of lipophilicity and acidity of a series of drugs and model chemicals and the values of pKa obtained in a study were found to correlate with the literature pKa data determined in water for a set of aniline derivatives studied.
Journal ArticleDOI
Reversed-phase liquid chromatographic separation of complex samples by optimizing temperature and gradient time III. Improving the accuracy of computer simulation.
John W. Dolan,Lloyd R. Snyder,R.G Wolcott,P. Haber,Tomasz Baczek,Roman Kaliszan,Lane C. Sander +6 more
TL;DR: This study has examined computer simulation errors that can arise from inexact expressions for retention time as a function of T, tG or isocratic %B, applicable to both complex and simpler samples, in either one- or two-dimensional optimization.
Journal ArticleDOI
Polyethylene-coated silica and zirconia stationary phases in view of quantitative structure-retention relationships
TL;DR: In this paper, the retention properties of two new high-performance liquid chromatographic (HPLC) stationary phases, polyethylene-coated silica (PECSiO2) and polyethylenescoated zirconia(PECZrO2), were compared chemometrically.
Journal ArticleDOI
Mechanism of separation on cholesterol-silica stationary phase for high-performance liquid chromatography as revealed by analysis of quantitative structure-retention relationships
Mehdi Ahmed Al-Haj,P. Haber,Roman Kaliszan,Bogusław Buszewski,Marta Jezierska,Zdzisław Chilmonzyk +5 more
TL;DR: It has been concluded that the new phase of cholesterol-silica stationary phase may possess valuable analytical specificity and its application for modelling penetration of xenobiotics through biological membranes appears rather unlikely.
