Ultra Inert Liners for GC

Agilent ultra inert liners feature a proprietary deactivation process intended to eliminate potential active sites located throughout the interior of the liner, providing low surface activity and predictable sample volatilization. This facilitates the reliable analysis of trace and active analytes without unintended inlet discrimination.

Agilent’s expansive line of CrossLab ultra Inert liners perform seamlessly with a variety of manufacturers’ instruments. Each Agilent UI liner is performance certified to ensure exceptional batch-to-batch uniformity. Delivered in exclusive Agilent touchless packaging, the pre-installed O-ring lets you quickly and easily install the new deactivated liner, saving time and improving productivity.

Inlet Gold Seals for GC

A GC gold seal (or gold inlet seal) enables leak-free seal between the inlet body and the capillary column ferrule. Even small leaks in the split/splitless gas chromatography (GC) inlet can reduce system sensitivity, causing poor signal-to-noise ratio and increased column bleed. The split/splitless inlet seal seals off potential microleaks within the flow path. The soft gold surface plating of the GC seals naturally deforms when compressed, ensuring that a leak-free connection is achieved between the base of the inlet and the analytical column. The injection molded design unique to Agilent ensures a highly polished surface, free of micro striations and tooling marks, and optimal plating adhesion.

Liner O-Rings for GC

A liner O-ring provides a gas-tight seal between the outside of the inlet liner and the weldment when the retaining nut is engaged. Also called a GC sealing O-ring, Agilent liner O-rings are a necessary component for both of the standard Agilent split/splitless and Multi-Mode Gas Chromatography (GC) inlets. Agilent offers a standard fluorocarbon O-ring compatible with most applications, and a graphite O-ring for inlet temperatures that exceed 350 °C.

Bleed Temperature Optimized (BTO) Septa for GC

Inlet septa are used to maintain a leak-free seal under the septum nut in the GC inlet, even after many repeated injections. The dimple in the middle of the septum guides the syringe needle through the inlet into the inlet liner to minimize damage to the needle and to ensure injection consistency. Bleed temperature optimized (BTO) septa are specifically designed for operation at temperatures up to 400°C without bleeding into the sample flow path. They ideal for use with low-bleed, mass-spec capillary columns and are preconditioned and ready to use.

Capillary Flow Technology (CFT) Supplies

Capillary flow technology (CFT) devices provide easy to make leak-free connections, simplify finding leaks, and increase the flexibility of the GC system. Using a backflush CFT device can decrease time in sample preparation. The GC system can now keep heavy contaminants from your analytical column and detection system.

Flame Ionization Detector (FID) Supplies

Flame ionization detection is the most commonly used GC detection method due to it's superior ability to measure hydrocarbons. Using a carrier gas, the sample is ionized via a hydrogen-air flame, then collected using a polarizing voltage. The current produced is measured and used to quantify the amount of sample being burned.
