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.

The Empore line of SPE disks comprises of the most complete line of SPE disks for extracting large volumes of aqueous samples. The product line ranges from time-tested C18 to unique phase chemistries such as carbon and the highly polar Oil & Grease disk. The disks are ideal for environmental analysis where 1 L sample volumes are not uncommon and provide an efficient alternative to LLE.

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

Application

Polymer-based SAX disk developed for the extraction of acidic compounds (e.g., carboxylic acids) from water samples and soil extractions. Amenable for the following methods:
  • EPA Method 548.1 - Endothall
  • EPA Method - Haloacetic acids and Dalapon

Exercise stimulates the release of molecules into the circulation, supporting the concept that inter-tissue signaling proteins are important mediators of adaptations to exercise. Recognizing that many circulating proteins are packaged in extracellular vesicles (EVs), we employed quantitative proteomic techniques to
