Solid Phase Extraction

Introduction

Solid phase extraction (SPE) is a sample preparation technique used in analytical chemistry to separate, purify, and concentrate specific compounds from a liquid mixture. It involves passing the liquid sample through a solid-phase material, typically packed in a column or cartridge. The solid phase material selectively retains the target compounds while allowing unwanted substances to pass through. After this selective retention, the analytes of interest are eluted from the solid phase using a suitable solvent. SPE is widely used in chromatography, environmental analysis, and drug testing to clean up and concentrate samples, removing interfering substances and improving the sensitivity and accuracy of analytical methods. It is a versatile and efficient method for a variety of applications, including the extraction of drugs from biological fluids, the purification of environmental samples, and the preparation of samples for instrumental analysis, contributing to the success and reliability of analytical procedures.
