The boiling point of a compound. A compound that boils at a temperature higher than the column temperature will spend all of its time to be condensed as a liquid. So high boiling point means a long retention time.
The solubility of the liquid phase. The soluble a compound which is in the liquid phase takes less time in being carried along by the gas. High solubility in the liquid phase leads to high retention time.
