Product Description

Our premium High-Temperature GC Injection Septa series is engineered for demanding gas chromatography and GC-MS applications requiring maximum thermal stability. Formulated to withstand continuous inlet temperatures from 340C up to 350C, these septa feature industry-leading low-bleed characteristics that drastically minimize siloxane release, preventing baseline drift and ghost peaks during high-sensitivity analytical runs.

This professional grade collection offers exceptional resealing capability and extended injection lifespans, featuring precision-molded designs for universal analytical ports, dedicated plugs for Shimadzu manual injection systems, and advanced Natural PTFE/Red Silicone double-layer composite structures. Fully pre-conditioned and ready-to-use, they ensure excellent mechanical durability and absolute carrier gas integrity straight out of the box.

Features

Where chemical inertness meets structural purity, our high-purity septa address your most rigorous laboratory compliance needs.

Vapor-phase silanized deactivation treatment eliminates surface active silanol groups, drastically reducing polar compound adsorption and peak tailing.

Advanced glue-free molecular bonding permanently fixes the PTFE/Silicone liners, completely eliminating adhesive residues and baseline ghost peaks.

Entirely manufactured and sealed within a certified GMP standard cleanroom environment, maximizing cleanliness for an ultra-low chemical background.

Molded from premium synthetic elastomer with high elastic memory, allowing over 100 reliable autosampler injections without carrier gas leaks.

Every batch undergoes stringent vacuum conditioning to guarantee absolute compatibility with sensitive capillary GC and GC-MS detectors.

FAQ

Quick technical answers regarding our cleanroom production, silanization methodology, and glue-free septa design to help your lab procurement.

What causes GC septa bleeding, and how do your high-temperature septa prevent ghost peaks?

Septa bleeding occurs when volatile siloxanes are thermally released from the silicone elastomer at high inlet temperatures, migrating into the column and generating ghost peaks or baseline drift. Our high-temperature GC septa undergo an advanced thermal pre-conditioning process during manufacturing. This eliminates trace volatile residues beforehand, ensuring ultra-low bleed levels even during continuous operation at 340C to 350C.

How do I choose between the molded brown septa (GCS03) and the PTFE/Silicone composite septa (GCS201)?

The GCS03 precision-molded brown septa are optimized for high-temperature auto-injection systems (up to 350C) where extended needle puncture life and excellent resealing are required. The GCS201 Natural PTFE/Red Silicone septa offer a double-layer design where the PTFE face provides absolute chemical inertness against aggressive solvents, making it ideal for trace analysis and highly sensitive GC-MS applications requiring minimal organic background interference.

Are these GC septa ready for immediate laboratory use, or do they require thermal pre-treatment?

All models in our high-temperature series (GCS01 through GCS201) are fully pre-conditioned, heavily baked, and hermetically sealed before packaging. No further conditioning or thermal pre-treatment is required in your laboratory. They are ready-to-use straight out of the box without risking contamination or analytical downtime.

What is the average puncture lifespan of the GCS03 molded 11mm septa under autosampler conditions?

The GCS03 features a precision-molded design that reduces structural stress during needle penetration. Under standard laboratory conditions using a properly aligned 26s-gauge autosampler needle, the GCS03 typically achieves up to 100 to 120 injections per

Is the GCS01 plug compatible with all models of Shimadzu gas chromatographs?

Yes, the GCS01 is specifically manufactured with precise dimensions (Diameter 5.5 mm x 7 mm, Height 7.5 mm) to perfectly fit standard Shimadzu GC manual injection ports, including popular series such as the Shimadzu GC-2010, GC-2014, and GC-2030. It ensures tight gas-dynamic sealing and withstands manual injection port environments up to 350C.
