Supra-Clean® and Supra-Poly® Solid Phase Extraction (SPE) - A Reference Notebook of SPE Applications

At PerkinElmer, we ,understand that sample ,preparation is one of the ,most critical steps in the analytical process. Often accounting ,for 60% of your timetable, it has a fundamental impact on a ,wide range of operational parameters. Any errors within this ,process undermine the quality of your data at all subsequent ,stages of your analysis. Solid Phase Extraction (SPE) helps ,avoid potential errors in sample preparation, reducing re-runs ,and dramatically increasing productivity. As one of the most cost-effective and ,flexible tools within the laboratory environment, SPE also provides efficient sample ,concentration and purification prior to many of today’s most popular analytical ,techniques, including HPLC, LC/MS, GC and GC/MS. This document is intended to ,provide you with the tools you need to quickly and efficiently develop extraction ,methods for your sampling analysis.
