Chapter 22, Problem 22.12P

Interpretation Introduction

Interpretation:

The half width of the peak for $\text{5}\text{μm}$ and $3\text{μm}$ particles has to be calculated.

Concept Introduction:

Peak width in chromatography is the full width of the peak at the half maximum. Half width peak $\left({\text{W}}_{\frac{\text{1}}{\text{2}}}\right)$ is calculated by the formula as follows:

    ${\text{W}}_{\frac{1}{2}}=\sqrt{\frac{\left(5.5\right)\left(\text{Plate}\text{height}\right){\left(\text{retention}\text{time}\right)}^2}{\text{Length}\text{of}\text{the}\text{column}}}$
