Our disks are produced by trapping sorbent particles within an inert matrix of polytetrafluoroethylene (PTFE). The resulting particle-loaded membrane yields a denser, more uniform extraction bed than can be achieved with traditional loosely packed SPE particles. The result is improved mass transfer kinetics with consistent performance in solid phase extraction methods. 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. The following performance gains can be realized:

  • ​Reduced solvent volumes
  • Small elution volumes
  • Reduced time for eluate evaporation
  • Potential elimination of eluate evaporation
  • High throughput
  • Channeling effects eliminated
  • Excellent reproducibility/low CVs
