Interpretation Introduction

Interpretation:

Reason behind maintenance of pH near the charge carried by weak acid has to be explained.

Concept Introduction:

Electrophoresis is separation of analyte as it travels from injector to detector end on the basis of charge and size of analyte.

Electroosmotic flow is defined as movement of certain fluid injected into fused-silica capillary that begins from anode towards cathode triggered by presence of applied electric field.

At high pH values, electroosmotic flow is stronger but since 4 is a low pH value, electroosmotic flow will be lower at this pH.
