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.

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.

Supplier: VARIAN

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.

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.

Supplier: VARIAN

This macroporous polystyrene product has a much higher loading compared to conventional functionalised silica SPE media and is compatible with all polar and non-polar, protic and aprotic solvents.

Supplier: VARIAN

MesoPore columns have been specifically designed to give optimum results in the analysis of prepolymers, i.e. polymeric materials with a large oligomeric component.

Supplier: VARIAN

The PLgel MIXED-LS series is a PS/DVB packing using an innovative proprietary suspension polymerization technique to virtually eliminate nano-particle leakage.

Supplier: VARIAN

Chromatography paper is used in thin layer chromatography applications such as evaluating radioisotope purity, QC testing.

These columns permit a simple, one stage clean-up as part of a methodology to determine pesticides in many organic matrices. The higher molecular weight fractions such as lipids, polymers, natural resins and dispersed high molecular weight components are easily eliminated in the GPC analysis.

Supplier: VARIAN

Polystyrene standards for many organic solvents either for conventional GPC column calibration or for calibrating light scattering and viscosity detectors that provide equidistant calibration points for greater accuracy.

Supplier: VARIAN

The CP-Chirasil-Dex CB phase consists of cyclodextrin directly bonded to dimethylpolysiloxane. This bond prevents the cyclodextrin from migrating to different locations in the surface film, delivering homogeneous enantioselectivity throughout the phase.

Supplier: VARIAN

Microsorb™ C18 is an octadecylsilane-covered silica that has been bonded using monofunctional bonding agents under optimised conditions. This material is then endcapped with trimethylsilyl groups to minimise nonspecific binding, maximise mass recoveries and improve peak shape.
