GC Syringes

Thermo Scientific syringes for GC instruments are designed to provide enhanced durability, clarity and accuracy in sample introduction. This gives confidence in analytical results, time-after-time. 

Durability in your GC syringe, The enhanced design of the syringes delivers:

• Improved solvent resistance
• Greater temperature range
• Increased operational smoothness
• Longer lifetime and improved cycle life

Clarity in your GC syringe

Syringes are provided with a clear, easy-to read black scale, which aids in consistent

delivery of samples for manual syringes and easy identification of installed autosampler syringes.

Accuracy in your GC syringe

The enhanced design of the syringe has eliminated areas where the sample can become trapped and potentially cause carryover:

• Closer fit between the plunger tip and PTFE insert at the zero position
• Tighter fit between PTFE insert and glass barrel
• Improved fixed needle attachment

In addition, the reduction in adhesive from the fluid path enhances durability and reduces the risk of sample interaction with the adhesive.

Syringe selection by needle gauge size

• Gauge is a measure of the “thickness” of the needle
• The higher the gauge number, the thinner the needle e.g. a 23 gauge is thicker than a 26 gauge
• Suffix “s” e.g. 23s refers to a needle with a narrower internal diameter
• For on-column injection ensure that the column ID is greater than the needle gauge

Available variety of GC Syringe for your instrument:

• GC syringes for Thermo Scientific TriPlus RSH Autosampler
• GC syringes for Thermo Scientific instruments
• GC syringes for Agilent instruments
• GC syringes for Shimadzu instruments
• GC syringes for CTC instruments
• Manual GC syringes

GC Liners

LinerGOLD GC liners

The GOLD standard in GC liner performance

• Increased accuracy and sensitivity in analysis – LinerGOLD prevents the loss of sensitive compounds in analysis
• Lower detection limits – when analyzing active and sensitive compounds
• Excellent reproducibility – gives confidence in your results from liner to liner – setting the GOLD standard

The GOLD standard in liner consistency

Consistency in your GC liner is of paramount importance – you expect to see a consistently high level of performance time after time. Thermo Scientific™ LinerGOLD™ GC liners are manufactured and tested to ensure that you have confidence with every liner that is installed onto your GC system.

GC Ferrules

Thermo Scientific ferrules are available in three different materials and various dimensions to match the instrument and capillary column ID. 

100% Graphite Ferrules

Thermo Scientific 100% graphite ferrules are a soft material that is porous to oxygen, making them suitable for most applications except GC-MS interface connections. These easy-to-use ferrules form a soft grip with the column and provide a stable seal.

15% Graphite / 85% Vespel Ferrules

The mechanically robust 15% Graphite/ 85% Vespel ferrules have a long lifetime and are compatible with GC-MS. These ferrules form a strong grip with the column and cannot be reused as they form a permanent seal with the column. They have a temperature limit of 350°C, but must be re-tightened after initial temperature cycles.

SilTite Metal Ferrules

The SilTite ferrule forms a strong, permanent, airtight seal around the capillary column, eliminating leaks. The base of the ferrule is flat and forms a perfect seal with the MS interface. The ferrule’s temperature tolerance is well above the limit of the injector, MS interface or GC oven. Unlike other ferrules, SilTite Ferrules do not need re-tightening after installation.
