(a)
Interpretation: The description of elution.
Concept introduction: A definition is used to describe the meaning of a term and this term can be a word, phrase, or other sets of symbols. There are two types of definitions and they are intentional definitions, which try to give the sense of a term and extensional definitions, which proceed by listing the objects that a term describes.

The volumetric flow rate of the fluid per unit cross sectional area of the column from which the fluid is flow is called linear flow velocity.
(i)
Interpretation: The description of selectivity factor.
Concept introduction: Chromatography is defined as the process of separating the mixture of substance or one material from another material or component of the substance or material.
(i)

Explanation of Solution
The ratio of the distribution constant of highly retained species of chromatography to the distribution constant of less retained species of chromatography is called selectivity factor.
The expression of selectivity factor is:
α=KBKA ....... (V)
Here, the distribution constant of highly retained species of chromatography is KB and the distribution constant of less retained species of chromatography is KA .
(j)
Interpretation: The description of the plate height.
Concept introduction: Chromatography is defined as the process of separating the mixture of substance or one material from another material or component of the substance or material.
(j)

Explanation of Solution
The ratio of the variance of chromatography to the length of the column is called plate height.
The expression of plate height is:
H=σ2L ........ (VI)
Here, the variance of chromatography is σ2 and the length of the column is L .
(k)
Interpretation: The description of the column resolution.
Concept introduction: Chromatography is defined as the process of separating the mixture of substance or one material from another material or component of the substance or material.
(k)

Explanation of Solution
In the chromatography, column is the pathway for the reaction to take place. The column resolution is obtained from the width of the first point and that of the second point.
The expression of Column resolution is:
RS=2ΔZWA+WB ........ (VII)
Here, the width of the pick at first point is WA and the width of the pick at second point is WB .
(l)
Interpretation: The description of the longitudinal diffusion.
Concept introduction: Chromatography is defined as the process of separating the mixture of substance or one material from another material or component of the substance or material.
(l)

Explanation of Solution
The process of migration of solute from a concentrated centre of a band of chromatography to the dilute region in other side of chromatography is called longitudinal diffusion.
