Influence of pH on Retention Behavior of Polyaniline-Coated Silica Gel Stationary Phase Investigated Using Linear Solvation Energy Relationships in Capillary Liquid Chromatography
2017
Abstract
The retention behavior of polyaniline-coated silica gel stationary phase was investigated under the varied mobile phase composition utilizing the linear solvation energy relationships approach in capillary liquid chromatography. Almost 80 solutes of various chemistries were employed to identify dominant retention interactions, to propose a possibly multi-modal retention mechanism and to describe the effect of a substantial change of eluent buffer pH.
