WebbGas chromatography separates according to vapor pressure and not boiling point. For example, if you have a non-polar column, but a mixture of alcohols and hydrocarbons, the higher boiling point alcohols will elite much sooner than the corresponding hydrocarbon of the same boiling point.

WebbPrinciple of gas chromatography: The sample solution injected into the instrument enters a gas stream which transports the sample into a separation tube known as the "column." … WebbInverse gas chromatography at infinite dilution has been used to study the effects of modifications of cationic (montmorillonite) and anionic (hydrotalcite) clays. By using alkanes and alkenes as probe molecules both the dispersive component of the surface energy and the surface acidic sites were characterized. The introduction of polymers … float with shade canopy
