Filters Filter Cartridges
Empore™ solid phase extraction cartridges are designed for sample pre-treatment to remove or minimize sample matrix and other interferences to clean-up a sample prior to analysis. Extraction cartridges incorporate C18 (Octadecyl) standard density sorbent particles with PTFE to create a mechanically stable sorbent disk secured in a syringe barrel.

  • Cartridge design and sorbent matrix promote high retention of a wide range of analytes, reducing method development time and facilitating a generic approach to sample preparation
  • High performance sorbents and proprietary Empore™ membrane technology offers high recovery, superior clean-up, and cartridge-to-cartridge reproducibility
  • Functional groups, such as octyl (C8) and octadecyl (C18), can be bonded to the silica surface to provide non-polar interactions
  • Each sorbent exhibits unique properties of retention and selectivity filter for a particular analyte

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.

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. Since the diffusion distance between particles is minimized, adsorption is more efficient, and extraction can be accomplished using low sorbent mass.

The standard density (SD) membranes for all silica based sorbent chemistries allow reliable sample preparation for challenging sample matrices. The membrane has been optimized for improved flow rates for samples processed in most bioanalytical applications. The Empore™ high density (HD) membrane formulation is effective for minimal elution volumes. These high density membranes are designed for maximum extraction efficiency with minimal elution volumes of samples that have less matrix interference.

Empore™ membranes efficiently extract samples with no channeling. The small bed volume allows compound elution from Empore™ cartridges in as little as 100 to 200 μl of mobile phase or mobile phase compatible solutions.

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.
