Chapter 27, Problem 27.4QAP

Interpretation Introduction

(a)

Interpretation:

The definition of retention volume is to be stated.

Concept introduction:

Retention volume is a quantity that corresponds to the product of retention time and volumetric flow rate of the solvent. The retention volume is proportional to the retention time. The flow rate of the solvent is the rate which is necessary for the operation to take place.

Interpretation Introduction

(b)

Interpretation:

The definition of corrected retention volume is to be stated.

Concept introduction:

The volume at the mean column pressure is known as the corrected retention volume. This volume is the product of retention volume and pressure corrected factor. Corrected retention volume is dependent upon the volumes of sample, detector and column.

Interpretation Introduction

(c)

Interpretation:

The definition of specific retention volume is to be stated.

Concept introduction:

The ratio of column temperature in Kelvin to the density of the liquid that is used in the stationary phase is called specific retention volume. It is influenced by the density of the liquid used for making the stationary phase and distribution constant of the solute.
