Manual and Autosampler GC Syringes – Hamilton Solutions for Gas Chromatography

Hamilton GC syringes are among the most critical components of sample introduction in gas chromatography. Accurate volume dispensing, minimal wear on the injector and septum, and a long service life are essential for both manual and automated GC systems.

Our website presents the most common GC syringe types and compatibility options, and we can help you select the right custom configuration.

Manual GC Syringes (Manual GC Syringes)

Standard GC Syringes

Volume range: 0.5 µL – 500 µL

Standard GC syringes are designed for split and splitless injectors. Non-coring needles reduce septum damage while ensuring consistent, repeatable sample introduction.

Available designs:

• Knurled Hub (KH)
• Cemented needle (N)
• Luer Tip cemented needle (LTN)
• Removable-needle design (RN)

Recommended applications:

• Routine GC analysis
• Organic solvents and volatile compounds

Purge and Trap GC Syringes

Volume: 5 mL and 25 mL

Syringes specifically designed for purge & trap applications, with a removable plunger for easier sample loading.

Typical applications:

• Drinking water and environmental analysis
• EPA purge & trap methods (e.g. 502.1, 503.1, 524.1, 524.2)

The robust mechanical design ensures a long service life even under heavy use.

SampleLock GC Syringes

Volume range: 50 µL – 100 mL

The SampleLock system enables samples to be collected, transported and dispensed safely without evaporative loss.

Benefits:

• Suitable for both gas and liquid samples
• Positive-locking plunger
• Minimised evaporation and environmental contamination
• Broad connectivity with different valves

On-Column GC Syringes

Volume: 0.5 µL and 10 µL

On-column injection introduces the sample directly into the capillary column, avoiding thermal stress.

Ideal for:

• Thermally sensitive compounds
• Low-boiling-point samples
• Measurements requiring high analytical accuracy

The long, fine-diameter needle enables precise positioning.

GC Autosampler Syringes (GC Autosampler Syringes)

Hamilton GC autosampler syringes are designed for automated sample introduction, where reproducibility, cycle life and a precise fit are essential.

Agilent GC Autosampler Syringes

Compatible systems:

• 7670, 7671, 7672 ALS
• 7683, 7693 ALS

Available designs:

• Cemented needle (N)
• Removable needle (RN)

Special connections

The design optimised for Agilent ALS systems ensures a long service life and consistent injection accuracy.

Bruker / Varian GC Autosampler Syringes

Compatible systems:

• 8100, 8200
• CP-8400, CP-8410
• CP-9010/9050
• CP-9020/9025

Special-connection and cemented-needle designs for stable and reliable sample introduction.

CTC / LEAP PAL GC and Headspace Syringes

Syringes available for CTC PAL systems:

• S-Line syringes – cost-effective solutions for general GC applications
• C-Line syringes – reduced sample-transfer loss
• HD-Type and HDHT-Type syringes – for high-temperature headspace applications (up to 200 °C)

Special plunger and sealing solutions ensure reliable sealing performance and a long service life.

GC Autosampler Compatibility with Other Manufacturers

Hamilton syringes are available for the following systems:

• Shimadzu (AOC-9, AOC-14, AOC-17, AOC-20)
• Thermo Finnigan (AI/AS 3000, AS 800/2000, HS 250/500/850)
• PerkinElmer (AutoSystem, Clarus GC)
• Waters GC systems
