Are gas chromatography and distillation pretty much the same?

Answer 1

They are very similar in the way that they separate compounds: by taking advantage of the difference in boiling point between compounds.

Distillation, however, is primarily used for the separation of two compounds in a mixture.

While gas chromatography is primarily used to identify compounds. It give you data about what compounds may be present in your sample. It's often paired with Mass Spectrophotometry so you could identify the compound in your mixture.
