Supplier: Restek

The Restek Cyano is a traditional monomeric cyanopropylsilane that is recommended for assays where alternate selectivity, or confirmation, to a C18 or C8 column is desired.

Supplier: General Separation Technologies, Inc.

GsBP™ GC columns with high quality column performances in all aspects.

Supplier: Restek

Viva columns are based on a wide pore material we designed for optimal large-molecule separations.

Supplier: YMC America,Inc

YMC-Pack C4 (butyl) columns are less hydrophobic than C8 or C18 packings, and generally utilize more aqueous eluents than either of these reversed-phase column types.

Supplier: Restek

Rxi® fused silica capillary GC columns are designed specifically for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity.

Supplier: YMC America,Inc

ODS-AM is a high quality analytical C18 material, with a very tight specification.

Supplier: Phenomenex

Cleanert® COOH SPE products consists of a propyl carboxylic acid on the inner silica surface.

Supplier: Restek

The Restek IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today.

Supplier: Restek

Restek’s polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.

Supplier: YMC America,Inc

These columns use tightly controlled, highly purified silica, a high-coverage C18 bonding, and a unique end-capping procedure utilizing lewis acid/lewis base chemistry.

Supplier: Restek

The Rtx®-200 column offers exceptional thermal stability, low bleed, and superior inertness—even for active compounds such as phenols, and with sensitive detectors such as ECDs, NPDs, and MSDs.

Supplier: Restek

These general-purpose columns are designed for solvent impurities, PCB congeners, simulated distillation, drugs of abuse, gases, natural gas odorants, sulfur compounds, essential oils, hydrocarbons, semi-volatiles, pesticides, and oxygenates.

Supplier: Restek

The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support.

Supplier: Restek

Pinnacle® DB PAH UHPLC columns are specifically designed to resolve complex mixtures of polycyclic aromatic hydrocarbons (PAHs).

Supplier: Restek

The Rtx®-65TG phase resolves triglycerides by degree of unsaturation as well as by carbon number.

Supplier: Restek

Unlike comparable wide pore columns with very broad distributions, Viva columns have a narrow distribution about the mean pore size, allowing a larger portion of the silica surface to interact in separations.

Supplier: Restek

Siltek® passivation technology enables these columns to offer unsurpassed inertness and the highest responses for active pesticides.

Supplier: Restek

Base-deactivated spherical silica is useful for normal-phase or HILIC separations.

Supplier: Restek

New Stabilwax®-MS columns ensure reproducible retention times from run to run, even with temperature cycling.

Supplier: Restek

Traditional PTFE tubing is gas permeable, difficult to pack with high efficiency, prone to shrinkage, and has poor thermal stability, so the Rt®-XLSulfur packed or micropacked column eliminates these problems.

Supplier: CUBE BIOTECH

The FPLC Cartridge assembly press is an efficient tool that simplifies the packaging process for FPLC columns.

Supplier: Ace Glass

This column is used in ASTM D1319-0, a 'test for hydrocarbon types in liquid petroleum products'. It consists of a charger section with a capillary neck, a separator section, and an analyzer section.

Supplier: Optimize

The OPTI-LYNX™ Guard Column is a high performance, cartridge-based guard system, suitable for use with any analytical column.

Supplier: Restek

Base-deactivated spherical silica is useful for normal-phase or HILIC separations.

Supplier: Hamilton

Hamilton guard columns protect analytical, semi-prep and preparative HPLC columns.

Supplier: Avantor

Bonded phases are more resistant to oxidation than non-bonded phases because of the stronger intermolecular forces produced by cross-linking.

Supplier: Restek

For the analysis of pesticides, PCBs, solvents, and drugs.

Supplier: General Separation Technologies, Inc.

Equivalent to: DB-624, DB-VRX, Rtx-624, Rtx-VMS, DB 502.2, VOCCol.

Supplier: Restek

Our C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase.

Supplier: Phenomenex

Innoval columns are packed with ultra pure silica particles which are prepared by aggregation of ultra pure silica sols.
