Empore™ Solid Phase Extraction (SPE) Cartridges

Empore™ Solid Phase Extraction Cartridges are designed for sample pretreatment to remove or minimize sample matrix and other interferences to “clean-up” a sample prior to analysis. Our extraction cartridge incorporates C18 (Octadecyl) standard density sorbent particles with PTFE to create a mechanically stable sorbent disk secured in a syringe barrel.
An Empore extraction disk is secured in place at the bottom of each cartridge with a sealing ring and a proprietary prefilter is placed above the Empore disk. This prefilter aids in preventing particulates and macromolecules from reaching the underlying membrane and improves the flow of biological samples, such as serum and plasma, through the cartridge.
Empore™ Disk Cartridges are an innovative alternative to packed column technology. Each cartridge is molded from a polypropylene resin. The dense particle packing and uniform distribution within Empore disks offer outstanding sample preparation efficiency and reproducibility of results. Since the diffusion distance between particles is minimized, adsorption is more efficient, and extraction can be accomplished using low sorbent mass.
