Fournisseur:  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.

Fournisseur:  WATERS
Description:   Specially designed for monitoring aldehydes in indoor air.
UOM:  1 * 20 ST

Fournisseur:  VARIAN
Description:   Bond Elut™ PH is a non-polar bonded silica material which exhibits a different selectivity to alkyl or aliphatic functionalised phases such as C8 or cyclohexyl. The electron density present in the aromatic ring affords an enhancement in the retention of conjugated or aromatic ring-containing analytes due to desirable pi-pi interactions.
Fournisseur:  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.
Fournisseur:  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.
Fournisseur:  WATERS
Description:   These cartridges can used with liquid and gas samples and have the unique capability of reverse flow direction, a useful feature for trace enrichment application.
Fournisseur:  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.
Fournisseur:  VARIAN
Description:   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.
Fournisseur:  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.

Fournisseur:  Beckman Coulter
Description:   This prep system kit isolates and purifies genomic DNA (gDNA) from whole blood. The kit is uses Solid Phase Reversible Immobilisation (SPRI) paramagnetic bead-based technology to effectively produce a high recovery of high quality DNA for downstream applications such as PCR.
UOM:  1 * 1 ST
Fournisseur:  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.
Fournisseur:  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.
Fournisseur:  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.
Fournisseur:  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.
Fournisseur:  VARIAN
Description:   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.
Fournisseur:  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.
