Theory behind gas chromatography
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.
