Ferrules

SGE manufactures an array of connection types for GC use. It is important to realize the factors that can be influenced by the connection type used. Poorly defined or selected connections can lead to an increase in dead volume, leaks from cycled temperatures and mismatched tubing sizes. Where possible, SGE recommends FingerTite™ solutions that eliminate the need for wrenches or other tools in your system.

When choosing ferrules ensure you consider the following:
  • Which material best suits your application?
  • What connection type do you want?
Graphite
Graphite Vespel®
SilTite®
SilTite® FingerTite

GC Ferrules Graphite

Your chromatography analysis does not end with the selection of the GC column. The combination of components selected for your instrument also make an important contribution to successful separations.

The SGE range of GC Connections improves your chromatography. Poorly defined or selected connections can lead to an increase in dead volume, leaks from cycled temperatures and mismatched tubing sizes.

Features and Benefits
  • Easy to use.
  • Forms a reliable seal.
  • Reusable.
  • Soft material, forms a soft grip to the capillary column.
  • Low emissions.

Recommended Applications

Column to injector and column to FID connections. Porous to oxygen, therefore unsuitable for connecting columns to mass spectrometers.

Product Specifications
  • Variety of hole sizes available for 1/16", 1/8", and 1/4" fittings.
  • 450°C temperature limit.
  • Variety of profiles available

GC Ferrules Graphite Vespel®

Features and Benefits
  • A composite of graphite and Vespel®.
  • Mechanically robust, hard material, long lifetime.
  • Forms a strong grip with capillary column.

Recommended Applications
MS interfaces.

Product Specifications
  • Variety of hole sizes available for 1/16", 1//8", and 1/4" fittings.
  • 350°C temperature limit.
  • Variety of profiles available.

GC Ferrules SilTite®

SilTite® metal ferrules have been developed specifically to overcome the problems associated with the use of 100% graphite and composite ferrules. SilTite ferrules form a strong and permanent airtight seal around the capillary column and have a temperature limit well above the temperature capacity of the injector, MS interface or GC oven. The metal SilTite ferrule together with the metal nut have the same coefficient of thermal expansion. The ferrule and nut expand and contract at the same rate eliminating any chance of annoying leaks. The nut does not need to be re - tightened after initial temperature cycles.

Features and Benefits
  • Strong seal on capillary columns - reduced air background.
  • No contamination - cleaner spectra.
  • Leak free - nut does not need re-tightening after initial temperature cycles.

Recommended Applications
MS interfaces.

Product Specifications
Kits available for Agilent, PerkinElmer, Shimadzu, Thermo Scientific, and Varian / Bruker GC - MS systems.

GC Ferrules SilTite® FingerTite

SilTite® FingerTite is a GC ferrule system that has been designed to be installed only with the force of you fingers, delivering an easy, leak and maintenance free seal.

Features and Benefits
  • Simplified installation process saves time.
  • Leak free - no column creep.
  • Cannot overtighten - no broken columns.
  • Chemically inert - no contamination.
  • Metal ferrule - no temperature limit.

Recommended Applications
MS, high throughput laboratories.

Product Specifications

Kits available for Agilent, PerkinElmer, Shimadzu, Thermo Scientific, and Varian / Bruker GC - MS systems.

Ferrules available with 0.4, 0.5, and 0.7 mm hole sizes. Blanking ferrules, replacement female nuts, and replacement Agilent base seals also available.
