General Purpose Septa for GC Aijiren’s general-purpose septa are made from an enhanced injection-molded silicone rubber material. The septa material, dark red or gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C.
The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone/PTFE or PTFE/natural red rubber. Our screw vials and vial screw caps are designed for both HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels
To prevent GC septum coring, don’t overtighten the septum nut, be sure to routinely replace your septum, and inspect your syringe (manual or autosampler) for tip damage. Also, consider switching to a softer, more pliable septum. Softer septa are less likely to core than firmer septa. Remember, however, that softer septa usually have a lower
Jul 10, 2012 · In past gas chromatographic (GC) analyses, it has been reported that septa of various makes release volatile organic compounds (VOCs) when subjected to high temperatures ( 1–9 ).These reports also revealed the frequent presence of contaminants such as finger oils from handling, or organic contaminants picked up during storage of these septa.

The mid-range advanced green septa combine low inlet adhesion properties with long lifetime and are recommended for GC applications. The blue septa offer a high-performance cost-effective alternative, offering a good level of inertness and are also recommended for GC applications. Septa come packed in a glass jar, for high purity.
A GC septum is located at the top of the injection port and serves two functions: 1) providing a leak-free seal to maintain carrier gas pressure inside the system 2) handling repeated puncturing by a syringe needle for sample introduction purposes without severe coring or leaking.
