Solid Phase Extraction: Fundamentals and Recent Developments


Solid Phase Extraction (SPE) has become a popular technique for sample preparation due to its convenience, effectiveness, relatively low solvent usage and versatility. The focus of this webinar is on SPE fundamentals, providing an overview of the available SPE phases as well as tips on how to choose the right phase for selected applications. The webinar will cover SPE method development with a close look at retention mechanisms and the role of pH in sample preparation. In addition, recent Supelco innovations in SPE and methods for current analytes of interest will be presented.
