Influence of the mobile phase and molecular structure parameters on the retention behavior of protonated basic solutes in chaotropic chromatography
(Elsevier Science BV, Amsterdam, 2017)
In this study, we present novel insights into the pH-dependent retention behavior of protonated basic solutes in chaotropic chromatography. To this end, two sets of experiments were performed to distinguish between mobile ...
The influence of salt chaotropicity, column hydrophobicity and analytes' molecular properties on the retention of pramipexole and its impurities
(Elsevier Science BV, Amsterdam, 2015)
The aim of this study was to examine the interaction of the chaotropic salts of different position in Hofmeister series (CF3COONa, NaClO4, NaPF6) added to the mobile phase with the stationary phases of different hydrophobicity ...
Retention mechanisms of imidazolin and piperazine-related compounds in non-aqueous hydrophilic interaction and supercritical fluid chromatography based on chemometric design and analysis
(Elsevier B.V., 2022)
The experimental design methodology based on central composite design of experiments was applied
to compare the retention mechanisms in supercritical fluid chromatography (SFC) and non-aqueous hy-
drophilic interaction ...
Investigation into the phenomena affecting the retention behavior of basic analytes in chaotropic chromatography: Joint effects of the most relevant chromatographic factors and analytes' molecular properties
(Elsevier Science BV, Amsterdam, 2015)
The aim of this study was to systematically investigate the phenomena affecting the retention behavior of structurally diverse basic drugs in ion-interaction chromatographic systems with chaotropic additives. To this end, ...
