ChemistryPrinciples of Instrumental Analysis(a) Interpretation: In order to obtain desired resolution of 1.5, the number of plates should be calculated. Concept introduction: The resolution can be calculated as follows: R = ( t R ) B − ( t R ) A ( t R ) B × N 4 4 R × ( t R ) B ( t R ) B − ( t R ) A = N N = [ 4 R × ( t R ) B ( t R ) B − ( t R ) A ] 2 where: N=Number of plates ( t R ) A , ( t R ) B =Retention times of species A and B respectively R=ResolutionStart your trial now!

Interpretation Introduction

**(a)**

**Interpretation:**

In order to obtain desired resolution of 1.5, the number of plates should be calculated.

**Concept introduction:**

The resolution can be calculated as follows:

Interpretation Introduction

**(b)**

**Interpretation:**

Height of the column should be calculated.

**Concept introduction:**

The plate height can be calculated as follows:

Interpretation Introduction

**(c)**

**Interpretation:**

Retention time of the methylcyclohexene should be calculated.

**Concept introduction:**

Retention time is directly proportional to the resolution. Therefore, following equation can be used.
