| Abstract: | Summary Retention parameters of different hydrocarbon classes were determined at 90–120°C on non-polar and medium-polar stationary phases. The specific retention volumes, and the thermodynamic functions of solution were calculated and the relationship between these data, the physicochemical properties and the chemical structure of the solutes (samples) and solvents (liquid phases) investigated. |
