Chapter 28, Problem 28.18P

(a)

Interpretation Introduction

Interpretation:

The purpose of solid-phase extraction prior to chromatography and the does the ion-exchange sorbent retain acrylamide has to be explained.

Concept introduction:

Solid-phase extraction:

Solid-phase extraction is a method for sample preparation.  Depending upon its physical properties and chemical properties of the compounds which are dissolved or suspended in a liquid mixture and separated out individually.
