Solid phase extraction cartridges, Bond Elut™ CBA

Dodávateľ: VARIAN
Opis: CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4,8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX and will demonstrate easier elution of quaternary amine functionalised analytes.

Solid phase extraction cartridges, Bond Elut™ Certify II

Dodávateľ: VARIAN
Opis: 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™ LMS

Dodávateľ: VARIAN
Opis: 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™ SI

Dodávateľ: VARIAN
Opis: 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™ C1

Dodávateľ: VARIAN
Opis: 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™ Sodium Sulphate Drying

Dodávateľ: VARIAN
Opis: 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.

Solid phase extraction cartridges, Bond Elut™ PPL

Dodávateľ: VARIAN
Opis: 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’.

Papír pro separaci fází, grade 1PS, Whatman™

Dodávateľ: Whatman products (Cytiva)
Opis: 1PS phase-separating paper is a hydrophobic filter for routine solvent extraction. Within seconds it retains aqueous phases, while solvent phases flow through.

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

Dodávateľ: VARIAN
Opis: 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™ CH

Dodávateľ: VARIAN
Opis: 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™ DEA

Dodávateľ: VARIAN
Opis: 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.

Solid phase extraction cartridges, Bond Elut™ Plexa PCX

Dodávateľ: VARIAN
Opis: 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.
