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
- Determination of diphenylarsinic acid, phenylarsonic acid and inorganic arsenic in drinking water: This study utilizes Empore SPE Disks for the simultaneous separation and preconcentration of toxic compounds in drinking water, highlighting the disks′ application in environmental safety and public health (Hagiwara et al., 2013).
- Monitoring of ecotoxicological hazard potential by polar organic micropollutants: The research emphasizes the utility of SPE disks in the environmental monitoring of micropollutants, contributing significantly to the assessment of water quality and ecological risks (Escher et al., 2008).
- Determination of commonly used polar herbicides in agricultural drainage waters: Demonstrates the efficiency of SPE Disks in analyzing herbicide residues in agricultural runoff, providing insights into pollution control and chemical residue management (Tran et al., 2007).
- Stability of pesticides on solid-phase extraction disks: Explores the stability of various pesticides on SPE disks under different conditions, proving the disks′ reliability for sample storage and analysis in multi-environmental studies (Cobb et al., 2006).
Other Notes
Developed for the mixed-mode extraction of polar and non-polar analytes from water samples and soil extracts. Offers unique selectivity for analytes that exhibit polar functional groups. Because the phase contains sulfonic acid functional groups, secondary SCX interactions can occur towards basic compounds that contain amine functional groups.
- Explosive residues (HDX, RDX)
