Empore™ Disk Technology: 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 high density membranes are designed for maximum extraction efficiency with minimal elution volumes for samples that have less matrix interference. Empore™ Solid Phase Extraction (SPE) Disks give you an efficient alternative to liquid/liquid extraction for sample preparation. A proprietary process is used to entrap adsorbent particles into a matrix of inert PTFE to create a mechanically stable sorbent disk. The disks can be used for purification and concentration of analytes from aqueous samples. Empore SPE disks provide a sample prep solution for large volume aqueous samples. This unique disk format provides a large surface area for sorbent/sample contact and fast flow rates along with high throughput may be realized with Empore solid phase extraction disks. The following performance gains can be realized:
- Reduced solvent volumes
- Reduced time for eluate evaporation
- High throughput
- Channeling effects eliminated
- Excellent reproducibility
