Supplier: Restek

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.

Supplier: Restek

Ultra amino columns are made of high-purity, spherical shaped type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications. Aminopropylsilane provides reproducible retention and efficiency for normal-phase or HILIC analysis of simple sugars.

Supplier: Restek

Free-Turn architecture lets you change cartridges by hand without breaking inlet/outlet fluid connections, with no tools needed.

Supplier: Restek

Highly retentive and selective phase for separating polar analytes, including polar acidic compounds. Compatible with highly aqueous (upto 100%) mobile phases. Highly base deactivated.

Supplier: Restek

Rxi®-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. These columns are ideal for GC-MS applications requiring high sensitivity, including use in ion trap systems.

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

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.

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.
