Quadrex GC Consumables

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.

GC CONSUMABLES – 1/16″ FERRULES AND 1/8″ REDUCING FERRULES

Model 8610C GC Mainframe

Quadrex offers a complete range of graphite and graphite/TL-Polyimide™ 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.

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

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.

GC CONSUMABLES – INJECTOR PORT LINERS

GC Injector Port Liner

Capillary injector port liners are a critical part of the capillary column system. They provide a clean, non-adsorptive injection zone which should be replaced regularly to avoid contamination from non-volatiles which can be deposited onto the capillary column. All injection port liners produced from precision borosilicate glass (quartz where noted) and are polysiloxane deactivated and ready for use. They are manufactured to exacting tolerances and come in various configurations for many popular GCs. Guaranteed inert for phenols, organic acids and bases.

Hot Tip HOT TIP:

TO BE SURE YOU HAVE CLEAN INJECTOR SYSTEM, CHECK YOUR LINERS WEEKLY, OR MORE FREQUENTLY IF RUNNING DIRTY SAMPLES.

SEPTA

Septa

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.

Hot Tip HOT TIP:

ALL SEPTA ARE PACKED IN CLEANED GLASS BOTTLES TO MAINTAIN PURITY. NEVER HANDLE SEPTA WITH YOUR FINGERS – THE OILS ON YOUR SKIN MAY CONTAMINATE THE INLET. ALWAYS USE TWEEZERS WHEN HANDLING AND INSTALLING SEPTA.

MARATHON SEPTA™

The advanced Marathon™ Septa have been specifically developed for use with autosamplers for long life. These septa typically achieve 400 injections or more without failure when used with dome-tipped needles (Agilent-style) and an autosampler or needle guide.

CARRIER GAS TRAPS AND FILTERS

GAS PURIFIERS – FROM CRS

  • Gas Traps
  • Advanced Filter System:  All NEW from CRS, this 2-part Advanced Filter System includes a small stainless steel manifold and a high capacity filter cartridge.
  • Oxygen Traps:  Oxygen is the leading cause of column degradation. These oxygen traps use a copper-based catalyst to remove oxygen to sub-ppm levels.
  • Moisture Traps:  Water which can be present in the carrier gas stream can hydrolyze common silanized supports which leads to stationary phase degradation.
  • Moisture/Oil/Dust Traps:  These traps are ideal for general purpose filtering such as fuel gases for FID’s.
  • Hydrocarbon Traps:  These traps use activated charcoal to remove all hydrocarbons except methane. Some hydrocarbon traps are available with Indicating Drierite™ for simultaneous water removal.
  • Specialty Traps:  The Split Vent Trap keeps detector emissions from contaminating your laboratory air.

 

Hot Tip HOT TIP:

CARRIER GAS CONTAMINANTS CAN LEAD TO GC COLUMN DEGRADATION, CAUSING INTERFERENCE WITH YOUR CHROMATOGRAPHY SUCH AS DECREASED SENSITIVITY AND INCREASED BASELINE NOISE

 

ADVANCED FILTER SYSTEM (AFS)

The Advanced Filter System (AFS) removes impurities such as oxygen, water and hydrocarbons from inert gases and hydrogen to low ppb levels. Proper installation of the AFS reduces impurities, increases sensitivity levels and improves performance.

The two part system includes a small stainless steel manifold and a high capacity filter cartridge. It can be attached to a laboratory wall or bench with brackets included. Each connection in the AFS is made with two fluoro-elastomer seals. The polycarbonate shield that surrounds the glass indicator section of the filter is sealed, so the gas flow is secure even if the glass is broken.

  • Excellent capacity and efficiency in one cartridge
  • All metal and glass construction
  • Visible indicators for both oxygen and water
  • Double seal construction for safety, especially when using hydrogen gas
  • Check valves protect gas lines during cartridge replacement
  • Recommended maximum flow rate is 1 L/min. at 200 psi maximum operating pressure
  • Easy cartridge replacement with twist on/off assembly knob
  • Expected life of =/> one year in typical use with up to 4 GCs
