Gas Chromatography

In this classic demonstration, from the Royal Society of Chemistry, volatile hydrocarbons are injected into a mock up of a chromatography column filled with washing powder. Natural gas is used as the carrier and once through, the column is burnt. As a sample of hydrocarbon emerges from the column, the flame will change in size and luminosity.

The resource provides a list of apparatus and chemicals needed for the experiment, together with teaching tips.
