Chapter 24, Problem 24.21P

Interpretation Introduction

Interpretation:

The description for change in retention time of Butanol on poly(ethylene glycol) column with increase in temperature has to be given.

Concept Introduction:

Retention factor:

The time that is necessary to elute that peak minus the minimum possible time for the travel of unretained solute through the column is called as retention factor. The retention factor is calculated using the equation,

$\text{k=}\frac{{\text{t}}_{\text{r}}{\text{-t}}_{\text{m}}}{{\text{t}}_{\text{m}}}$

Where,

${\text{t}}_{\text{r}}$ = retention time

${\text{t}}_{\text{m}}$ = minimum possible time for the travel of unrestrained solute through the column.

The retention time can be calculated using the formula of retention factor,

$\text{k=}\frac{\text{K}}{\text{β}}$

Here, $\text{k}$ = retention factor

$\text{K}$ =partition coefficient

$\text{β}$ = phase ratio
