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 chamber. A carrier gas transports the sample into the GC column. A mass spectrometer (MS) or other detector at the end of the column measures components in the compound.
In syringe injection systems, high-quality GC septa are critical. These GC accessories need to introduce the sample without leakage and withstand the high-temperatures of the GC inlet. If a GC septum decomposes under these conditions, septum bleed can cause baseline disruption and ghost peaks in the GC chromatogram. GC septa include both disc-shaped products and Shimadzu plugs.
GC septa from SSP are formulated and manufactured using ultra pure silicone elastomers and then conditioned for:
- Ultra Low Bleed
- High Temperature Resistance (240C)
- Long Lasting (multiple injections)
- Resist Coring
SSP can also supply you with custom GC septa based on your specifications. All our GC septa are made in the USA at our Ballston Spa, New York facility.
