Supplier: Agilent

Each method validation kits contain three HPLC columns with the same column type (i.e., bonded phase, particle size, configuration) but from different manufacturing lots.

Supplier: Agilent

Virtually equivalent to (50%-Phenyl)-methylpolysiloxane column. They are solvent rinsable and very low bleed mid-polarity columns ideal for GC/MS. They are suitable for CLP pesticides.

Supplier: Agilent

DB-17ht provides improved resolution for triglycerides and is ideal for confirmational analyses at elevated temperature.

Supplier: Agilent

These MolSieve 5Å columns have wide range of tubing materials including stainless steel, ultimetal and nickel plus hundreds of stationary phases, packings, and supports to suit many specific application.

Supplier: Restek

Fused capillary columns for high-temperature applications such as mineral oil extraction and analysis.

Supplier: Merck

Suplex pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL LC-ABZ columns. These specially deactivated columns differ in that Suplex pKb-100 is not endcapped, while SUPELCOSIL LC-ABZ is endcapped. The absence of the end-capping reagent results in better performance from Suplex pKb-100 for the strongest basic compounds, while LC-ABZ is preferred when the sample also contains acids and/or zwitterions.

ZORBAX® Eclipse Plus HPLC columns are the ideal first choice for method development of all samples.

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: Merck

Discovery® BIO Wide Pore reversed-phase columns satisfy the need for efficiency, selectivity, scalability, and reproducibility for RP HPLC analyses of proteins, peptides, and small biomolecules.

Supplier: Restek

Highly selective phase for polar analytes. Compatible with highly aqueous (up to 100%) mobile phases. Silica manufactured by Restek.

Supplier: Agilent

Features and benefits for the low thermal mass column modules, or the LTM II.

Supplier: Restek

Integra-Guard® columns are designed for leak-free connection between the guard column and the analytical column. The guard column section is marked separately from the analytical column, using high-temperature string.

Supplier: Agilent

JW DB-Petro is a 100% dimethylpolysiloxane phase, precision-engineered for the analysis of PONA, PIANO and PNA from petroleum processes.

Supplier: Agilent

DB-ProSteel metal columns are virtually unbreakable, and are available in a wide variety of stationary phases.

Supplier: Agilent

Bond Elut™ C18 is a hydrophobic silica sorbent. C18 is commonly used for non-polar compounds. Bond Elut™ C18 is endcapped to reduce interactions with silanol groups.

Supplier: Restek

Raptor™ Biphenyl column is extremely useful for fast separations in bioanalytical testing applications like drug and metabolite analyses, especially those that require a mass spectrometer (MS).

Supplier: Restek

These Ultra biphenyl columns are made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

Ultra C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape. It is made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Supplier: Restek

These biphenyl columns offer a greater degree of dispersion than conventional phenyls and a greater degree of polarizability than phenyl hexyls, creating higher selectivity and a greater range of usability. Because of these heightened interactions, this column shows substantial increases in retention—especially for dipolar, unsaturated, or conjugated solutes—and enhanced orthogonal selectivity when using methanol mobile phases.

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These general-purpose C8 columns are suitable for a wide range of compounds from acidic through slightly basic.

Supplier: Restek

Aqueous C18 is a rugged, reversed-phase column with a well-balanced retention profile. It can effectively retain more types of solutes than a conventional C18 and is ideal for multicomponent LC-MS analyses. The general-purpose Aqueous C18 boasts high reproducibility and compatibility with many mobile phase conditions - even 100% aqueous. And when used with a gradient, it eliminates the all-too-common issue of multiple compounds eluting near the column void time.

Supplier: Agilent

ChiraDex columns allow for direct racemic separations without derivatisation.
