General description

Empore membrane SPE technology comprises of SPE particles tightly enmeshed within a network of inert PTFE fibrils (90% SPE particles : 10% PTFE, by weight). The SPE-membrane fabrication process results in a highly dense and uniform extraction medium that offers distinct advantages over traditional sorbent/packed-bed SPE products. Empore SPE technology provides a denser, more uniform extraction bed than traditional packed bed products allowing for smaller bed weights, shorter analyte to pore diffusion paths, and more efficient extractions.

Layed above the SPE membrane is a polypropylene pre-filter to prevent particulates from reaching the underlying membrane. The dense particle packing and uniform distribution within the Empore membane offers outsanding extraction efficiency and reproducibility.

Save Time & Money:
  • Reduced SPE Bed Mass = Reduced SPE Solvent & Elution Volumes
  • Minimize SPE eluate evaporation time
  • Potentially allows for direct injection of the SPE eluate
  • Dense & Uniform Extraction Medium = No SPE Channeling and Voiding
  • Efficient mass-transfer kinetics allow for faster flow rates
  • Eliminate SPE fines improving column and instrument life

Features and Benefits

  • Reduced sample and elution volumes
  • Reduced time for eluate evaporation
  • Increase sampling throughput
  • Eliminate channeling effects
  • High and reproducible recoveries

Other Notes

Recommended for the extraction of moderately-polar to non-polar analytes from aqueous samples (e.g., biological plasma).
