Question

The basis of the technique of chromatography for separating components of a mixture is :

• A. the differing movement of particles of different mass in an electric field
• B. the absorption of infrared radiation by the components
• C. the interaction of the components with both stationary and mobile phases
• D. the deflection of charged particles in a magnetic field

Answer 1

The correct option is C the interaction of the components with both stationary and mobile phases

Chromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase.
