Gas chromatography consists of a gas chromatographic system, carrier gas and a gas chromatography column that is either packed or capillary. Capillary GC columns are commonly used as they provide low bleed, consistent results, and better efficiency than packed columns. In gas chromatography, compounds are separated primarily based on their boiling points and intermolecular interactions such as London dispersion force, Pi-Pi interaction, Dipole-Dipole interaction, Dipole- Induced Dipole interaction and Hydrogen Bonding Interaction.
