2. Chromatographic properties of carbon dioxide-based mobile phases

2.1 Thermodynamic aspect

2.1.1 Influence of density

As in CPL, retention depends on solute-stationary phase, solute-supercritical fluid and supercritical fluid-stationary phase interactions. Solute-supercritical CO ₂ interactions can be governed by varying its pressure and, hence, its density (figure 6 )
