Abstrakt: Retention of 17 organic compounds was studied in high-temperature liquid chromatography mode on Hypercarb porous graphitic carbon with subcritical water as an eluent. Three different eluent temperatures were studied: 150, 175 and 200 °C. Abraham solvation parameters model was used for quantitative evaluation of retention data. It was found that increase of eluent temperature from 150 to 200 °C results in decrease of cavity formation system parameter v from 2.9 to 1.7. No clear tendency can be observed for temperature dependency of other system parameters.
