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.

Microprobes, stainless steel, to remove septum and ferrule pieces in fittings

Supplier: Restek

This direct injection liner adapter uses standard 1,59 mm capillary nut and ferrules. Can be used with Agilent or Restek direct injection glass inserts or Restek direct injection uniliner liners for an Agilent 5890 packed column GC.

Supplier: Restek

This kit includes a ¹/₄" stainless steel nut and graphite ferrule for attaching the liner to the GC inlet and a ¹/₄ to ¹/₁₆" stainless steel reducer, plus a ¹/₄" and 0,5 mm ID graphite ferrule for attaching the column to the liner.

Supplier: Restek

Microseal septum incorporates two separate sealing mechanisms. These sliding seals eliminate septum coring and the resulting accumulation of septum crumbs in the injection port liner. The septum uses a 23-gauge (0,63 mm, 0,025”) needle or probe with a blunt, truncated conical tip. Since the syringe plunger end details are determined by manual or autosampler compatibility. The advantages of the septum include elimination of septum coring, longer life, consistent and low needle insertion force.

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.

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

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.
