Webnearly all of its time condensed as a liquid at the beginning of the column. So high boiling point means a long retention time. The solubility in the liquid phase. The more soluble a compound is in the liquid phase, the less time it will spend being carried along by the gas. High solubility in the liquid phase means a high retention time.

Vapor pressure The boiling point of a compound is often related to its polarity (see also polarity chapter). The lower the boiling point is, the higher the vapor pressure of the compound and the shorter retention time usually is because the compound will spent more time in the gas phase. great wall hyde park
