What are the common materials used in SPE for catalysis?
SPE cartridges or disks are often packed with a variety of materials such as silica gel, alumina, ion-exchange resins, and polymeric sorbents. The choice of material depends on the specific application and the nature of the analytes. In catalysis, these materials are chosen to selectively adsorb catalysts, reactants, or products, thereby enabling detailed analysis and characterization.
