Opis: VF-1ms is a highly inert, non-polar, low bleed GC column providing increased sensitivity over a broad array of applications.

Dodávateľ: VARIAN

Opis: The CP-Si™l line consists of a range of stationary phases which are based on a polysiloxane backbone. Functional groups are added to the polymer to introduce selectivity. Each polymer used for the CP-Sil line is manufactured in-house and is optimised to obtain highest degree of reproducibility.

Opis: VF-35ms is a medium polarity column, which is the ideal choice for trace environmental and chemical analyses, and as a confirmation column.

Dodávateľ: VARIAN

Opis: These columns are ideal for high speed applications such as high throughput screening, process monitoring or tracking changes in MW distributions where time is the most critical factor in the analysis.

Opis: 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.

Opis: 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.

Opis: The MetaSil AQ materials are based on silica that is highly coated with hydrophobic alkyl chains interspersed with hydrophilic short-chain endcapping groups. These columns remain fully extended in aqueous phases, allowing increased interaction between samples and the bonded phase.

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.
