Interpretation Introduction

(b)

Interpretation:

The reason as to why two monomethyl esters of N-acetyl-L-aspartic acid could be separated by cation-exchange chromatography at pH=3.0 but could not be separated by cation-exchange chromatography at pH=7 is to be stated. The explanation for the corresponding answer is to be stated.

Concept introduction:

Cation-exchange chromatography is a type of separation technique in which anion resin is used in the chromatography column. This anion resin interacts with the cation part of the sample and retards their follow in the column. The neutral compound follows easily on this chromatography column.
