Question
The gas-solid chromatography is ______________ chromatography as per basic principle involved.
a. Adsorption
b. Absorption
c. Exclusion
d. Ion-exchange
Solution
The gas-solid chromatography is a type of Adsorption chromatography as per basic principle involved.
Here's why:
-
In gas-solid chromatography, the stationary phase is a solid on which the analyte molecules are adsorbed.
-
Adsorption is a surface phenomenon where molecules of a component in the gas phase are concentrated on a solid surface.
-
The separation of components in the mixture is based on their differing degrees of adsorption on the solid surface.
-
Therefore, the basic principle involved in gas-solid chromatography is adsorption, making it an Adsorption chromatography.
