GC CONSUMABLES - 1/16" FERRULES AND 1/8" REDUCING FERRULES

GRAPHITE AND GRAPHITE/TL-POLYIMIDE™ FERRULES

Quadrex offers a complete range of graphite and graphite/TL-Polyimide^TM ferrules for capillary column installation which offer a reliable gas tight seal and are specifically designed for use in your GC. When choosing the ferrules you need, remember that there really isn't a "standard" ferrule or GC fitting. Most instrument manufacturers and ferrule suppliers have their own particular designs and dimensions for these components, so be sure you're selecting the ferrules which were designed for your particular GC. This will insure that your column installation will be leak-free.

GRAPHITE FERRULES FOR 1/16" FITTINGS

Graphite ferrules are highly suitable for fused silica capillary column installation and are preferred for high temperature GC applications. Upper temperature is 450°C. The pliability of this type of ferrule allows them to be used in any GC fitting.

Column I.D. / O.D.	Quadrex #	PRICE
0.10mm/ 0.20mm	GF-10	$25.00/pk. 10
0.18-0.20mm/ 0.35mm	GF-25	$25.00/pk. 10

GRAPHITE FERRULES FOR AGILENT GCs

Agilent's standard injector and detector fittings are such that they require a shortened ferrule design. The graphite ferrules below are specifically for Agilent GCs.

GRAPHITE/TL-POLYIMIDE FERRULES FOR 1/16" FITTINGS

We now have the direct molded-to-size ferrules made with graphite/TL-Polyimide. These ferrules are superior to graphite-Vespel™ ferrules. They have superior thermal properties, seal easier (they are a little softer with a Rockwell hardness of approx. 75 -vs- 95 to 102 for Vespel™), don't off gas, and have a much lower coefficient of thermal expansion.

FERRULE REMOVAL TOOLS

This is a useful set of tools which remove ferrules that have become imbedded in nuts or fittings. The spiral tapered tip screws into the ferrule easily and grabs tightly on the way out. Useful on ferrules with 0.4mm to 0.8mm I.D.'s.

Hot Tip

hard yet pliable, graphite-vespel ferrules can be re-used up to 6 or more times before requiring replacement. over tightening any ferrule would cause deformity and shorten the ferrule lifetime.
