Question
Chapter 27, Problem 27.18QAP
Interpretation Introduction
(a)
Interpretation:
The variables that lead to band broadening are to be stated.
Concept introduction:
The band broadening is defined as a phenomenon. It leads the poor chromatographic performance and resolution which results in the reduction of the separation efficiency. This problem is responsible for both the quality and accuracy of the separation.
