Question

Chromatography technique is used for the separation of:

• A. small sample of mixture
• B. plant pigments
• C. dye stuffs
• D. all of the above

Answer 1

The correct option is D all of the above

Chromatography technique is used for the separation of a small sample of a mixture, plant pigments, dyestuffs. The sample components are partitioned between the mobile phase and the stationary phase.

Note:
In adsorption chromatography, the mobile phase will be liquid as well as gas. The stationary phase will be solid. In column chromatography, the mobile phase is the solvent and the stationary phase is silica gel. In gas chromatography, the mobile phase is carrier gas.
