Solid phase extraction cartridges, Bond Elut™ SI

Supplier: VARIAN
Description: Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut™ SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.

Solid phase extraction cartridges, Bond Elut™ PPL

Supplier: VARIAN
Description: Bond Elut™ PPL is a styrene-divinylvenzene (SDVB) polymer that has been modified with a proprietary non-polar surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease of flow for viscous or particulate rich water samples, while the high surface area and strong hydrophobicity ensure reproducible extractions with high recoveries upon elution. Bond Elut™ PPL is suitable for EPA Method 528 ‘Determination of Phenols in Drinking Water by SPE and Capillary GC/MS’.

Solid phase extraction cartridges, Bond Elut™ Plexa PCX

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ CH

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ Diol

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ LMS

Supplier: VARIAN
Description: Bond Elut™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

Solid phase extraction cartridges, Bond Elut™ C1

Supplier: VARIAN
Description: Due to the methyl group and subsequent low carbon load, Bond Elut™ C1 is the least retentive of all alkyl group bonded phases for non-polar compounds. However, due to the extensive end capping of this sorbent to mask polar silanol activity, retention and elution of polar and multi-functional analytes can still be achieved. Typical applications include plasma, urine and aqueous samples.

Solid phase extraction cartridges, Bond Elut™ Certify II

Supplier: VARIAN
Description: Bond Elut™ Certify II was developed specifically for the rapid and effective extraction of acidic drugs and metabolites from urine and other biological matrices. Certify II is a mixed-mode cartridge packed with non-polar C8 and strong anion exchange (SAX) sorbent. It has been optimised for acidic drugs such as 11-nor-delta-9-tetrahydrocannibinol-carboxylic acid, salicylic acid, ibuprofen, acetaminophen and other compounds that possess both non-polar and anionic characteristics.

Solid phase extraction cartridges, Bond Elut™ NEXUS and NEXUS WCX

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ DEA

Supplier: VARIAN
Description: Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.

Glass block manifolds, HyperSep™

Supplier: Thermo Fisher Scientific
Description: Vacuum manifolds for HyperSep™ SPE columns allow easy processing of samples.

Solid phase extraction cartridges, Bond Elut™ PSA

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ PBA

Supplier: VARIAN
Description: PBA is a unique sorbent consisting of a phenylboronic acid covalently linked to a silica gel surface. Covalent processes result in a higher retention to the sorbent surface than other mechanisms, resulting in superior clean-up. The boronate group has a high specificity for cis-diol containing compounds such as catechols, nucleic acids, low molecular weight proteins and carbohydrates.

HyperSep™ Hypercarb™ SPE columns

Supplier: Thermo Fisher Scientific
Description: Flat, 100% porous graphitic carbon (PGC) with selectivity for structurally similar compounds, offering separation of compounds with simple solvents. Hydrophobic reversed phase; normal phase adsorption; polar retention.

Solid phase extraction cartridges, Bond Elut™ PRS

Supplier: VARIAN
Description: Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

SLE plates, 96-well, HyperSep®

Supplier: Thermo Fisher Scientific
Description: HyperSep® SLE provides a fast and effective sample preparation technique for removal of phospholipids from biological matricies. HyperSep® SLE deals with sample preparation of biological matricies via a simple, efficient and an effective protocol, the focus being the removal of interfering phospholipids which cause a number of issues for end point analysis.
