• 1
• 2
• 3

What is chromatography?

• A way to see pretty colors

• A laboratory technique used to separate a mixture.

• A form of distillation

Separation is achieved in gas chromatography due to the components in the mixture having different

• Interactions with the stationary phase.

• Colors

• Solubility in the moving solvent.
