Role of derivatization in gas chromatography

Some points on role of derivatization in gas chromatography are:

• Derivatization replaces active hydrogen atoms with nonpolar substituents that raise analyte vapor pressure.
• It converts highly polar compounds into neutral derivatives that can readily enter the gas phase.
• Derivatization reduces strong intermolecular attractions that otherwise limit volatilization under GC conditions.
