Physico-chemical methods for the chromatographic materials heterogeneity evaluation
The characterization methods used in the analysis of the chemical structure, microstructure and morphology, as well as the physical properties, of the chromatographic support are varied. This paper will focus on some techniques often used for the investigation of polymer/silica stationary phases. Many of these techniques are specific for characterization of particular properties of phases, and the properties of phases are also discussed correspondingly. To fully understand structure-property relationships, several characterization techniques are presented.
