Question
Chapter 28, Problem 28.11QAP
Interpretation Introduction
(a)
Interpretation:
The order of the compounds from a normal-phase packed HPLC column is to be stated.
Concept introduction:
The mobile phase is non-polar in nature and the stationary phase is polar in nature in the normal phase packing chromatography. The compound which has the most polar nature will put at the last. And the compound with the less polarity is placed at the first stage of the group.
