dc.description.abstract This study investigated the influence of temperature on the specific retention volumes ( o g V ) of 13 volatile organic compounds (VOCs) in silicon oil as the liquid stationary phase using gas liquid chromatography (GLC). Temperature was varied from 303.15K to 423.15K to allow transport calculations for different seasons. Four PDMS polymers with average molecular weight ranging from 760 to 13 000 were used as solvents. Linear plots of log Vg against 1 T were obtained in all cases permitting predictions and interpolations to temperatures not studied here and also dependable enthalpies and entropies of solute transfer from the mobile phase to the stationary phase can be calculated. The specific retention volumes reported in this work are in agreement with literature for similar systems. Efforts were taken to ensure the best possible accuracy and trace the possible sources of error. We devised a gas liquid chromatographic system which secured a simple retention mechanism and showed reproducible solute retention over a long period of time. en_US
