Thermolite Plus septa are a proven low-bleed champion. With a maximum temperature of 350 °C, Thermolite Plus septa are suitable for most applications. BTO septa are bleed and temperature optimized with a maximum temperature of 400 °C, for the most demanding GC and GC-MS applications.

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.

Turn off the carrier gas. Remove the GC column. Remove all injection port consumables (including items such as the injection port liner, inlet seals, septa, fittings, etc). If possible, choose at least one polar solvent and one non-polar solvent which will not contaminate your instrument.

Our Suba-seal rubber septa are available in different dimensions, ideal for air and moisture sensitive chemistry procedures. After piercing with a non-coring needle, rubber closes the puncture, protecting the contents of vessel or container from atmosphere.

Choosing the right GC inlet supplies—Restek Topaz liners, septa, inlet seals—and implementing a rigorous and timely preventative GC inlet maintenance schedule can help ensure optimum performance, maximum reproducibility, and minimized downtime for your lab.

Septa for use with general chromatography vials PTFE/Red Rubber Septa: (PTFE/RR) PTFE/Red Rubber septa are the most popular and economical choice for general gas chromatography applications. These septa are used primarily for routine analysis in gas chromatography with FID, TCD and FPD detectors. PTFE/Red

Injection port septa used in gas chromatographic analyses should exhibit low bleed, resist leaks, and be easy to penetrate. For years, Thermogreen LB-2 septa have been considered by many as the benchmark GC septa for these parameters due to several performance advantages over other commercially available septa. A new generation

Aijiren Technologies septa are the only GC injec-tion port septa that are plasma treated prior to being packaged in an individually sealed blister pack in a clean room environment. The blister pack, while certainly being a convenient size for easy storage, most importantly ensures that the septa stay clean until they are ready to be installed

It must provide a barrier that is readily penetrated by the injector needle whilst maintaining internal pressure without contaminating the analysis. They are generally

GC Septa The GC septum should be routinely replaced to reduce the risk of leaks and septum particle contamination. In fact, if the instrument is in heavy use, change the septum daily. Repeated use of the same septum will result in increased coring, which may introduce a leak and/or result in septum fragments being deposited in the inlet liner.

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. GC Inlet Septa Portfolio. Figure 1.

Catalog number: 31303211. Ensure optimal performance of your GC instrument with bleed and temperature optimized Aijiren Tech™ BTO and TR-Green Septa. Made of low-bleed silicone, these septa have excellent mechanical properties, are ideal for demanding GC-MS applications, and may be used reliably up to 400 °C. 48 (Blister Pk.)

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. You can have confidence in your chromatographic results knowing
