Question

In adsorption chromatography, the stationary phase is:

• A. solid
• B. liquid
• C. gas
• D. any one of the above

Answer 1

The correct option is A solid

Adsorption equipment is used to bind molecules or particles to a surface. This process is used for the reclamation or remediation of process effluents including wastewater, liquid, gas, vapour, air and contaminated soil.

Adsorption chromatography is probably one of the oldest types of chromatography around. It utilizes a mobile liquid or gaseous phase that is adsorbed onto the surface of a stationary solid phase.

The equilibration between the mobile and stationary phase accounts for the separation of different solutes.

Option A is correct.
