Empore™ SPE Disks

Description

• 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 VolumesMinimize SPE eluate evaporation timePotentially allows for direct injection of the SPE eluateDense & Uniform Extraction Medium = No SPE Channeling and VoidingEfficient mass-transfer kinetics allow for faster flow ratesEliminate SPE fines improving column and instrument life
• Application: Developed for the extraction of volatile and highly polar compounds from aqueous samples. Applications include:Ground water - N-nitrosdeimethylamineWaste water - Oxamyl and methamidophosDrinking water - TrihalomethanesReagent water - Clean-up for purge and trap applicationsForensics - Fire accelerants, combustible vapors
