"Solid Phase Extraction"

The water-wettable, hydroxylated exterior allows excellent flow, even with biological fluids. A gradient of polarity on the polymer surface shunts small analytes to the more hydrophobic centre of the polymer bead, where they are retained prior to the washing and elution steps. Plexa provides these performance enhancements due to a unique polymeric architecture with a non-retentive, hydroxylated, amide-free surface and a non-polar PS/DVB core for retaining small molecules.

Bond Elut™ CH is a mid-polarity sorbent that exhibits unique selectivities for certain analytes. When employed as a non-polar sorbent, CH has the approximate polarity of a C₂ sorbent. Bond Elut™ CH is often a good choice when non-polar sorbents such as C₁₈, C₈ or C₂ do not provide the desired selectivity.

Clean PP reservoirs contain two PP frits pre-inserted, an ideal configuration for simple filtration.

Bond Elut™ NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged) and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol and SI sorbents, Bond Elut™ NH₂ is excellent for the separation of structural isomers.

Supplier: VARIAN

Bond Elut™ PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut™ NH₂. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut™ NH₂.

Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.

Bond Elut™ Diol (2OH) resembles unbonded silica in its tendency for strong hydrogen bonding with analytes. 2OH can also be employed in the non-polar mode because the hydrocarbon spacer on its functional group provides enough non-polar character for retention of hydrophobic analytes. Bond Elut™ Diol is a listed SPE device for the DIN 14333-1 method on benzimidazole fungicides.

Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Bond Elut™ Jr cartridges have top and bottom Luer fittings allowing easy sample processing when used in conjunction with standard SPE cartridges. Bond Elut™ LRC cartridges have a large reservoir above the sorbent bed and are suitable for use on any standard SPE vacuum manifold.

Bond Elut™ NEXUS is an ultra-clean polymeric sorbent which has bi-modal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no pre-conditioning required. The large particle size makes NEXUS ideal for extractions from highly viscous samples, such as horse urine.

Based on the same base polymer technology, Bond Elut™ NEXUS WCX is a weak cation exchange sorbent that offers extra selectivity for analytes, such as quaternary ammonium drugs and anabolic steroids.

Die Mikroextraktion durch gepackte Sorbentien (Micro Extraction by Packed Sorbent, MEPS™) ist eine Neuentwicklung auf dem Gebiet der Probenvorbereitung mit SPE (Solid-Phase Extraction / Fest-phasenextraktion). Das MEPS™-Produkt besteht aus zwei Komponenten, und zwar aus der MEPS™-Spritze und dem MEPS™-Kanüleneinsatz BIN (Barrel Insert and Needle Assembly). Für die Probenvorbereitung mit MEPS™ stehen folgende Sorbentien zur Verfügung: Umkehrphasen, Normalphasen, Mischmodus und Ionenaustauscher. Da die MEPS™-BINs für kleine Probenvolumen (bis unter 10 µl) verwendet werden können, eignen sie sich sehr gut für den Online-Einsatz im Rahmen von LC-MS-Analysen von Proben mit geringem Volumen.
