Silicone-based septa are typically used for both GC inlet seals and sample introduction. They have a centered hole for guiding the syringe needle. Quality and performance of septa have a direct effect on application results (reliability and accuracy), column lifetime and instrument condition. A good practice is to check and change septa as often as needed.
● Septa are made of two different processed silicone material: Advance Green (AG) and Bleed and Temperature Optimized (BTO). BTO temperature limit is 400.C, and AG temperature limit is 350.C. Both are preconditioned and ready to use.
● Packaged in a glass jar. Septa are offered in different sizes depending on the GC instrument configurations. Check the GC instrumentation specifications for details.
