Chapter 26.7, Problem 3TY

Interpretation Introduction

Interpretation:

The hydrodynamic injection time should be calculated.

Concept introduction:

Hydrodynamic injection time:

If electrophoresis is conducted in a capillary tube the time taken for the injection is known as hydrodynamic injection time and it given by below equation.

$\text{Time}\text{(t)}\text{=}\frac{{\text{128ηL}}_{\text{t}}}{{\text{ΔPπd}}^{\text{4}}}$

Where,

$\Delta \text{P}$ is the pressure difference

$\text{η}$ is the sample viscosity

$\text{d}$ is the capillary inner diameter

${\text{L}}_{\text{d}}$ is the total length of the capillary

$\text{t}$ is the injection time
