Objective of Solid Phase Extraction (SPE)

Separation and Purification of Target Analytes

Making use of solid phase extraction to separate and purification a target analytes are described in the following two methods

Types of SPE

Currently the following types of solid phase extractions are available.

General Four Steps

The general use of solid phase extraction is in four steps, as shown in the figure below.

Procedure for solid phase extraction

In general, there are 3 solid phase extraction sampling methods (as shown in the below) as well as a gravity based system. For quick and reproducible sample pretreatment by solid phase extraction, the suction method and the pressurization method are good methods. Variety of easy-to-use peripheral equipment and automatic solid phase extraction systems are available.
