The Laboratory Gas Chromatography category covers equipment and consumables used to separate, identify and quantify components in complex samples using controlled flow paths, columns, gases, detectors and supporting sample hardware. These products are not isolated purchases, because their performance is tied to the sample, surrounding equipment and the way the wider method is carried out. A practical point for this category is that high-precision syringes from Hamilton ensure that exact, reproducible volumes are delivered to the inlet, which is critical for the accuracy of your quantitative analysis and the longevity of your injection port.
Leaks, contamination, unsuitable materials or poorly matched consumables can reduce sensitivity and make retention or identification less reliable. A well-matched setup balances analytical technique, sample chemistry, pressure and flow requirements, and material compatibility, helping the laboratory avoid unnecessary rework, difficult cleaning or premature replacement.
The complete method includes sample preparation, compatible vials or tubes, a stable carrier or mobile phase, separation hardware, detection and appropriate data review. The same principle applies across pharmaceutical, chemical, food, environmental, forensic and research laboratories: control the inputs, use compatible equipment and document the conditions that can influence the result. As part of the Chromatography Equipment and Supplies range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Gas Chromatography Range
Our collection covers the main product groups used to separate, identify and quantify components in complex samples using controlled flow paths, columns, gases, detectors and supporting sample hardware, from gas generators through to GC consumables.
Laboratory Gas Generators
The Laboratory Gas Generators range brings together products designed to separate, identify and quantify components in complex samples using controlled flow paths, columns, gases, detectors and supporting sample hardware. Zero Air generators, such as the Peak Precision series, actively remove hydrocarbons (to <0.05 ppm) and moisture, which is essential for stable baselines in FID detectors.
Laboratory GC Columns
The Laboratory GC Columns range brings together products designed to separate, identify and quantify components in complex samples using controlled flow paths, columns, gases, detectors and supporting sample hardware. A smaller internal diameter generally provides higher efficiency and resolution, while larger diameters (like 530µm) offer higher sample capacity and easier injection.
Laboratory GC Consumables
The Laboratory GC Consumables range includes instruments, accessories and consumables used to separate, identify and quantify components in complex samples using controlled flow paths, columns, gases, detectors and supporting sample hardware. Trajan syringes are designed with tight tolerances and plunger-to-barrel fits that prevent sample carryover and ensure high-precision volume delivery.

Frequently Asked Questions
Are these columns compatible with major GC hardware brands?
Columns and consumables from Macherey-Nagel and Trajan Scientific are designed to be fully compatible with major chromatography systems, ensuring seamless integration into your existing laboratory infrastructure. Laboratories should compare sample chemistry, pressure and flow requirements, and material compatibility and document the selected setup for consistent use.
Why should I use a gas generator instead of high-pressure cylinders?
Gas generators from Peak Scientific provide a safer, more consistent supply of carrier gases like hydrogen or nitrogen, eliminating the safety risks and purity fluctuations associated with frequent cylinder changes. The final choice should reflect sample chemistry, pressure and flow requirements, and material compatibility, as these points influence day-to-day compatibility and repeatability.
How do I choose the correct GC column for my application?
Selection depends on the polarity and boiling points of your analytes. We offer a wide variety of stationary phases from Macherey-Nagel and Trajan Scientific to ensure optimal separation for everything from non-polar hydrocarbons to highly polar acids. Before ordering, confirm sample chemistry, pressure and flow requirements, and material compatibility and any accessories or consumables needed for routine use.
How often should GC consumables like septa and liners be replaced?
To prevent ghost peaks and peak tailing, septa should be replaced every 50-100 injections. High-quality consumables from Hamilton and Trajan Scientific are designed to minimise bleed, but regular maintenance is essential for sensitive detectors like MS or FID. The final choice should reflect sample chemistry, pressure and flow requirements, and material compatibility, as these points influence day-to-day compatibility and repeatability.
What are the benefits of using precision syringes for GC injection?
High-precision syringes from Hamilton ensure that exact, reproducible volumes are delivered to the inlet, which is critical for the accuracy of your quantitative analysis and the longevity of your injection port. The final choice should reflect sample chemistry, pressure and flow requirements, and material compatibility, as these points influence day-to-day compatibility and repeatability.
