Key Definitions â–¸
Inert Flow Path
A fully deactivated internal surface engineered to minimize adsorption, degradation, or interaction of active analytes during GC sample introduction and transfer.
Bleed Temperature Optimization (BTO)
A process that conditions GC septa to reduce bleed at high temperatures, improving MS sensitivity and reducing noise in trace-level analyses.
Ultra Inert (UI) Deactivation
Agilent’s advanced treatment applied to seals, liners, press-fits, and flow-path components to eliminate active sites and ensure highly reproducible chromatographic performance.
Inlet Discrimination
A selective loss of heavier or less volatile analytes during vaporization. Proper liner geometry and deactivated surfaces help minimize discriminatory effects.
Transfer Line
Tubing used to move analytes between GC components—such as from the inlet to the detector—where inertness and thermal stability are critical for preventing adsorption and carryover.
Ferrule
A compressible sealing component that provides a leak-tight connection between a GC column and instrument hardware, available in graphite, Vespel, metal, and composite materials.
Frequently Asked Questions â–¸

Why should I choose genuine Agilent GC consumables?

Genuine Agilent consumables are engineered to exact system specifications, ensuring proper sealing, inertness, and long-term performance. They reduce contamination, prevent leaks, and deliver reliable, reproducible chromatography.

How often should common GC consumables be replaced?

Parts such as inlet liners, septa, ferrules, and O-rings experience wear from heat and repeated injections. Regular replacement—based on method, sample type, and usage—helps prevent system drift and maintains consistent performance.

Are Agilent consumables compatible with all GC systems?

Agilent consumables are optimized for Agilent GC and GC/MS instruments. Some items may fit other systems, but only genuine Agilent parts guarantee validated performance, correct fit, and full inertness within Agilent flow paths.

Can Chrom Tech help identify the right consumables for my GC?

Yes. As an authorized Agilent distributor, Chrom Tech provides expert support to match your instrument model and application with the correct consumables and replacement parts.
