Graphite ferrules are commonly used in GC systems on the inlet and detector ends because they don’t stick to the column, and can be removed and reinserted easily. They should not be used with GC/MS instruments because of permeability to air.

Supplier: Merck

These porous polymers, based on 2,6-diphenyl-p-phenylene oxide, are widely used as an adsorbent in both air collection and purge trap applications.

Supplier: Trajan Scientific and Medical

These GC ferrules are made from 100% PTFE. They are soft, completely inert, and have very low friction.

Septa, BTO premium high-temperature GC septa, Ø: 10 mm, Max. temp.: 400 °C

Supplier: HAMILTON BONADUZ

Long Life GC autosampler septa are designed for use with GC autosamplers.

Supplier: Trajan Scientific and Medical

Vespel GC ferrules are made from 100% high-temperature polyimide, a hard polymeric material that tends to seal permanently to capillary columns when in use. A firm torque is required to compress and seal.

Supplier: Restek

Graphitized carbon black offers unique selectivity and very little adsorption for alcohol analyses. CarboBlack packings are treated with KOH or picric acid for basic or acidic compounds, and special alcoholic beverage loadings are available. CarboBlack supports provide resolution and retention similar to Carbopack™ and Carbograph supports.

Advanced Green 3 low-bleed GC septa is a premium septa for autosamplers in all critical analyses.

Supplier: Trajan Scientific and Medical

Marathon long-life center guide GC septa are ideal for standard manual injection GC and GC/MS.

Supplier: Trajan Scientific and Medical

General purpose blue GC septa, maded of silicone combines significantly longer injection life, low bleed and low injection port adhesion.

Supplier: Trajan Scientific and Medical

Reliabily against the carrier gas pressure in the inlet. Capable of being pierced and resealing time after time without pieces of the septa being deposited in the GC inlet system. Does not contaminate or bleed material into the chromatographic system.

Supplier: Trajan Scientific and Medical

Vespel/graphite GC ferrules are made from quality polyimide/graphite blend. They seal with minimal torque and can be reused and repositioned along capillary columns if not over compressed in the fitting. Due to slight shrinking at high temperatures, they must be retightened after initial temperature cycles to avoid leaks.
