GC CONSUMABLES - FERRULES, LINERS, SEPTA, SYRINGES, TRAPS AND FILTERS

Quadrex offers a complete line of GC consumables that most often requiring routine replacement.

GRAPHITE AND GRAPHITE/TL-POLYIMIDE™ FERRULES* More Information

Quadrex offers a complete range of graphite, graphite/TL-Polyimide™, and graphite-Vespel™ ferrules for capillary column installation which offer a reliable gas tight seal and are specifically designed for use in your GC. Standard 1/16" ferrules are available for the most popular GCs such as HP-5890 and 6890s, Varian, Perkin Elmer, Shimadzu, Finnegan and others.  Ferrules for 1/8" fittings and reducing ferrules (1/8" to 1/16") and two-holed ferrules are also available.

INJECTOR PORT LINERS More Information

All injection port liners are polysiloxane deactivated and ready for use (other deactivation available, inquiry for details). They are manufactured to exacting tolerances and come in various configurations for many popular GCs. Guaranteed inert for phenols, organic acids and bases.

SEPTA More Information

Advances in GC techniques can lead to higher injection port temperatures. At elevated temperatures, septa can stick to the injection port hardware or harden causing leaks which can lead to poor reproducibility. Septa coring is also a problem which results in debris entering the injector liner and possibly even the capillary column itself. Today's septa technology provides outstanding mechanical properties for repeated manual or autosampler injections, and chemical properties which give ideal low bleed characteristics for elevated temperature use.

CARRIER GAS TRAPS AND FILTERS More Information

Today's GC column systems rely on the highest purity carrier gases in order to avoid interference's with the chromatography. To achieve this it is important to filter out any contaminants that may be present in your compressed gas sources. Individual gas purifiers are available to filter the contaminants commonly found in compressed gas cylinders. All of the following gas purifiers are produced using the finest grade of adsorbent media. The housings are constructed with strength, durability and simplicity of design in mind. All traps and filters are supplied with nickel plated end fittings in either 1/8" or 1/4" sizes.

Hot Tip 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 WILL CAUSE DEFORMITY AND SHORTEN THE FERRULE LIFETIME.
