Rubber septa Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis. PTFE is protective layer that once broken exposes rubber to chemical attack. Types of rubber septa PTFE/red rubber – AC6, 6RT1

GC septa from SSP are precision-molded from ultra-low bleed silicone rubber. These laboratory septa protect the purity of your samples and help maintain the pressure of carrier gases such as nitrogen, argon, hydrogen, or helium. GC septa also support split injections for packed columns and split-less injections for capillary columns.

2016/07/01 · The septum nut acts as a heat sink that maintains the septum temperature between 75–100 °C below the inner inlet temperature. Septum temperatures vary a lot between different inlet systems, but typically for a 300 °C split–splitless inlet the septum will run at around 250 °C.

CRS Endura-Seal GC septa are resilient to needle wear and tear, eliminates coring and are recommended for automated analysis that requires long run times. Endura-Seals are a patented alternative to typical silicone-rubber injection port septa for gas chromatography. They work in a 2-part sealing system that includes the septa and the sealing nut.

Inlet septa. The Inlet septa is an essential part of the sample introduction into a GC system. The purpose of the septa is to create a barrier which is penetrated readily from the nozzle needle and is maintained while the internal pressure is held up without contaminating the analysis. Septa are available in a number of different materials and

2020/10/19 · Septa replacement is one of our most common tasks when doing routine GC inlet maintenance on our gas chromatographs. Fortunately, it is also one of the easiest! In this example, we replace the septum in an Aijiren gas chromatograph. The steps may vary on a different instrument or configuration. Additional Resources
