Supplier: Trajan Scientific and Medical

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.

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

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: Merck

SPME-GC inlet liners are designed for optimum sample introduction for specific injection techniques that are suitable for Agilent, Perkinelmer, Shimadzu, Finnigan, Varian and Thermo scientific equipped with split/splitless inlets.

Supplier: Merck

Ready to use GC septa for inlet temperature of up to 100 to 350 °C.

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.

Supplier: VWR Collection

Almost all septa have one laminated side with PTFE (high chemical resistance) and form an inert barrier between carrier material and sample.

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.
