"GC Columns"

Supplier: Thermo Fisher Scientific

The SilTite µ-Union is a connector for GC capillary columns, giving zero dead volume. It has low thermal mass, is only 9 mm in length and has a mass <0,5 g.

Supplier: Merck

Inlet liners used in an GC require an O-ring placed near the top for proper operation. This O-ring ensures that the only path for carrier gas to get to the outside of the inlet liner is through the grooves in the inlet seal at the bottom of the injection port.

Supplier: Thermo Fisher Scientific

Exceptionally inert mid-polarity columns with selectivity and elution order optimised for difficult separations.

Supplier: Restek

The Rt®-βDEXcst columns are specially designed for the fragrance industry and pharmaceutical applications.

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

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: AGILENT HEWLETT PACKARD

DB-5.625 is specially processed to exhibit excellent inertness for EPA semivolatile methods 625, 1625, 8270, and CLP protocols.

Supplier: Restek

These fused silica columns are processed for high temperature applications such as high molecular weight hydrocarbons.

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: MACHEREY-NAGEL

Nonpolar silarylene GC phase with low bleeding for envrionmental analysis.

Supplier: VARIAN

Column type: GC kolonne, Columns used for cumene analysis, Ø indv.: 0,53 mm, Længde: 50 m

Supplier: Restek

Optimised for pesticide analysis by US EPA Method 608.

Supplier: Restek

Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and DEX columns continue to demonstrate stability after hundreds of temperature program cycles. 2,3-di-O-methyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane.These are excellent column for most chiral compounds in essential oils.

Supplier: AGILENT HEWLETT PACKARD

These columns contain 100% dimethylpolysiloxane.

Supplier: Restek

Application-specific columns for volatile organic pollutants. Recommended in U.S. EPA methods for volatile organic pollutants.

Supplier: Restek

The Rt®-βDEXsp columns are useful in dual-column configurations, with the Rt-βDEXsm column, for complex enantiomeric separations.
