The CP-Cyclodextrin-β-2,3,6-M-19 column separates many optical isomers that could not be analyzed previously.

Supplier: VARIAN

These specialty solid phase extraction cartridges provide higher retention of small organics, including those that are too polar to retain on C18 or polymeric SPE.

Supplier: Agilent

Poroshell 120 is made with a superficially porous particle that has a solid silica core and a porous outer layer. This particle provides high efficiency at lower pressures and is ideal for fast or high-resolution separations of many types of analytes.

Supplier: VARIAN

Bond Elut™ NH₂ is a weak anion exchanger and is a good choice for retention of very strong anions that may be irreversibly retained on other anion exchange sorbents.

Supplier: VARIAN

Lower bleed rate than Fused Silica, best column lifetime and accurate results.

DB-225 is ideal for separations of cis- and trans-fatty acid methyl esters in food testing applications.

Supplier: VARIAN

Florisil is a magnesia-loaded silica gel, extremely polar in nature and ideal for the isolation of polar compounds from non-polar matrices.

Supplier: Agilent

Recommended columns for semivolatiles, halogenated compounds, pesticides, herbicides, drugs of abuse, amines, unknown sample screening.

Supplier: VARIAN

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

Supplier: Agilent

ZORBAX® Extend-C18 columns have high efficiency and a long life at high pH upto pH 11,5 with more effieincy and better peak shape than polymer-based columns.

Supplier: Merck

Fast nano-LC for proteins and peptides. Chromolith® CapRod® capillaries combine the speed of monolithic silica technology with the sensitivity of nano-LC, thus enabling high speed high sensitivity LC-MS analytics.

Supplier: VARIAN

Individual pore size GPC columns offer high resolution over a specific molecular weight range. The linear portion of the calibration curve, where the slope is at its shallowest, defines the MW region over which optimum resolution will be achieved.

Supplier: VARIAN

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.

Supplier: VARIAN

Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Supplier: VARIAN

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.

Supplier: VARIAN

Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Supplier: Agilent

Eclipse Plus columns are recommended for initial method development from pH 2 to 9 and provide high resolution and excellent peak shape of all types of compounds.

Supplier: VARIAN

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.

Supplier: Merck

The Discovery® HS F5 (PFP) HPLC Column provides excellent peak shape and stable, low-bleed LC-MS separation.

Supplier: VARIAN

Bond Elut™ C2 is a fairly non-polar sorbent because of the short chain length of the functional group. C2 is often used during the process of method development if analytes are retained too strongly on a C8 or C18 phase. The polarity of C2 is slightly lower than a cyano phase for polar interactions.

Supplier: Merck

Ascentis®Phenyl HPLC columns are optimised to the three terms of the resolution equation: efficiency, retention, and selectivity.

Supplier: Agilent

Agilent ZORBAX® Eclipse XDB-C8 columns provide four bonded phase choices for method development optimisation.

Supplier: Agilent

These columns are not bonded or cross-linked, and are therefore useful for established methods that do not require the column to have cross-linked or bonded polymer phases. Because SE series columns are not bonded or cross-linked, solvent rinsing is not recommend.
