Solid-Phase Extraction > SPE Disks Products & Reviews

Empore extraction disks provide a high flow rate solution for large volume sample preparation, and are available in a variety of bonded phases. The Empore disks are available in two diameters, 47 and 90 mm. By increasing the diameter of the disk used, the disk surface area available for sample passage increases, resulting in better solvent flow rates through the disk.

Bond Elut SPEC is a monolithic sorbent bed manufactured with ultraclean polypropylene plastic and bonded-silica impregnated on a glass fiber disc, resulting in an SPE product that delivers faster sample processing and lower costs. 

• 47 mm glass fiber disks embedded with styrene/DVB resin. • For chlorinated, benzidine-containing, or nitrogen-containing pesticides. • Meet requirements of EPA Methods 515.2 and 553.

SPE Disks with PS-DVB sorbent for environmental applications, 47mm diameter, 20/pk

Commonly used for the solid phase extraction of analytes from complex sample matrices.  A variety of functional groups, such as octadecyl (C18) and octyl (C8) can be bonded to the silica surface to provide non polar interactions.  Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte.  The choice of which sorbent is best for a particular method will be influenced by the percent…

SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction.  SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked.  It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.

SDB-RPS is a poly(styrenedivinylbenzene) copolymer that has been modified with sulfonic acid groups to make it hydrophilic.  SDB-RPS is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked.  The sulfonation imparts unique selectivity for organic analytes that are polar in nature, such as drugs, drug metabolites, water-soluble pesticides and pesticide metabolites.  SDB-RPS is also u…

Cation-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with sulfonic acid.  Note that Cation-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked.  The functional group imparts selectivity for cationic analytes, such as primary, secondary and tertiary amines.

3M Bioanalytical Anion-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with quaternary ammonium groups.  Note that the 3M Anion-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked.  The functional group imparts unique selectivity for anionic analytes, such as Endothall, Dalpon and haloacetic acids.

The Oil & Grease Disk was specifically designed for EPA Method 1664 (N-Hexane Extractable Materials (HEM) and Silica Gel Treated N-Hexane Extractable Material (SGT-HEM) by Extraction and Gravimetry).  EPA Method 1664 Revision A was approved for use in the United States and published in the Federal Register on May 14, 1999.  The Oil & Grease Disk incorporates C18 sorbent particles within a hydrophobic matrix. For EPA Method 166…

Empore™ Chelating Disks provide a way to selectively remove multivalent metal cations from solutions.  This selectivity can be used to concentrate metals from a sample for analysis or to isolate and remove metal interferences from a complex organic or inorganic sample matrix.  In the latter case, the purified filtrate is ready for use.  The chelating disk has an affinity for multivalent (primarily 2+ and 3+) transition element…

Empore Carbon Disks are designed for the extraction of volatile, highly polar, and water soluble compounds from aqueous solutions.  The Empore Carbon Disk provides all the advantages of activated carbon in a compact and thin Empore Disk.
