Chromatography Separation Ink
Product Code : EL-C-10972
Quick answer: Chromatography Separation Ink is a mixture of cyan, magenta and yellow inks that looks black but splits into its three bright colours when spotted on chromatography card and run with a solvent such as water, or separated by electrophoresis. One bottle gives about 500 spots. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the chromatography experiment is done
Paper chromatography separates the components of a mixture because each one is held by the paper (the stationary phase) and dissolves in the solvent (the mobile phase) to a different degree. As water soaks up the card, the dye that is most soluble and least held by the paper moves furthest, so the single black spot opens out into separate bands of cyan, magenta and yellow.
The result shows students that a colour which looks pure can be a mixture, and it gives three clear bands from which Rf values can be measured. The same ink can also be separated by electrophoresis, where the dyes move through a moist medium in an electric field instead of being carried by a solvent.
- Draw a pencil line about 2 cm from the bottom of a strip of chromatography card or paper.
- Put a small spot of the ink on the line and let it dry.
- Stand the strip in a beaker with water below the line, and cover the beaker.
- Remove the strip when the water is near the top, mark the solvent front and let it dry.
- Measure each coloured band and calculate its Rf value.
