Fornecedor: Restek

Descrição: General purpose columns for arson accelerants, essential oils, hydrocarbons, pesticides, PCB congeners (e.g. Aroclor mixes), sulfur compounds, amines, solvent impurities, simulated distillation, oxygenates, gasoline range organics (GRO), refinery gases.

Fornecedor: Restek

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

Fornecedor: Restek

Descrição: An intrinsically base-deactivated (IBD) phase, containing a polar group within, or intrinsic to, the hydrocarbon bonded phase. Unique selectivity and a high level of base deactivation, while reducing or eliminating the need for mobile phase additives.

Descrição: 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.

Descrição: 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.

Fornecedor: Restek

Descrição: 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.

Descrição: 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.
