Chromatography Columns

Chromatography columns separate molecules within mixtures during gas or liquid methods. Filled with stationary phase compositions or resins, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual polarity, composition, and size.

In-line biocompatible guard cartridges

Supplier: VICI JOUR RESEARCH

The in-line PEEK guard cartridges extend the life of analytical columns by trapping contaminants from the sample and mobile phase, thereby preventing loss of retention. Only PEEK and titanium contacts the mobile phase and sample. This system is ideal for use with proteins or other biopolymers that may be contaminated or absorbed by steel surfaces.

Solid phase extraction cartridges, Bond Elut™ C18 EWP

Supplier: VARIAN

Bond Elut™ EWP is based upon standard particle size silica but with 500 Å pores to allow more efficient extraction of large molecules (>15000 MW), which are typically excluded from standard porosity silica phases.

Solid phase extraction cartridges, Bond Elut™ SI

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.

Solid phase extraction cartridges, Bond Elut™ NH₂

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.

Solid phase extraction cartridges, Bond Elut™ SAX

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.

Solid phase extraction cartridges, Bond Elut™ C18 OH

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.

Solid phase extraction cartridges, Bond Elut™ C8

Supplier: VARIAN

Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.
