Aijiren''s general purpose septa are made from an enhanced injection-molded silicone rubber. The septa material, gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 C.
GC Septa. GC septa from Specialty Silicone Products (SSP) are used in gas chromatography (GC), a group of techniques for separating and analyzing volatile compounds. In GC systems, a sample is injected through a rubber septum into a heated vaporization chaer.

Septa Rubber or silicone discs which are used inside the injector for introduction of sample into the chromatographic system. The syringe needle penetrates this disc at the time of sample injection Ferrule A plug made from graphite or grass for holding the
A comparative study with commonly employed septa of various types and makes under varying analytical conditions, e.g., injection port temperature, carrier flow rate, capillary column type and oven
However, direct injection techniques tend to concentrate the volatiles on the column head and amplify bleed:it is extremely important to use low-bleed septum for these appliions. It is worthwhile noting that while bleed tends to decrease over time as the septum becomes conditioned, the likelihood of column degradation as the result of oxygen permeating the septa increases.

Introduction 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 ().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.

China Different Shape borosilie glass gc headspace vials for gc USA Simple approach for the preparation of 15−15N2 We injected 5 mL 15−15 N 2 gas to 160 mL non-degassed (0 ar) and degassed water (950 ar) which created a bubble of 0.58 ± 0.10 cm 3 (mean ± s.d., n = 12).
Injection port septa If the GC column is not causing ghost peaks, where should you look next? One of the most common sources is injection port septa. I wrote the following post to help identify and fix this issue. Troubleshooting Injection Port Septa To test
Also, use for both the inlet and detector con- figurations on Aijiren 6890, 5890, and 7890 GC systems (Short ferrules provide a robust seal and typically remain tight over time). Caution:For safety, please use common sense when handling metal surfaces within the GC oven, including the Cool-Lock Nut.
