COLUMN CHROMATOGRAPHY

It started with an empty tube
Filled with a murky green liquid,
Clumps of plant clung on to the sides.
Left to settle, the plant material and liquid eventually separated,
Like oil and water.

Extracting the liquid from the test tube,
We mixed it into a combination of ethanol and silica.
The solvent tore it apart
The greasy, darker liquid sank to the bottom,
While the lighter, purer liquid remained at the top.

In the dark room, the UV light coated the mixture,
Reverting colours never seen before.
Neon! Red! Bands of colour!
Who knew that a purple light could transform simple liquid
Into a work of art?
