2016/07/01 · While gas chromatographers may take their septa for granted, in fact these small and seemingly unremarkable polymer disks keep air out of the carrier-gas stream when used in an inlet and keep samples intact and uncontaminated when used in sample vials. Choosing the wrong septa can compromise method accuracy and repeatability as well as reduce column life

Specialty Silicone Products (SSP) makes autosampler septa, gas chromatography (GC) septa, bonded caps, magnetic caps, EPA/VOA septa, cap mats, and re-sealable septa. We manufacture our products in Ballston Spa, New York (USA) under strict quality control at

Bleed temperature optimized (BTO) inlet septa are preconditioned and ready to use with low-bleed, mass spec capillary columns. Our long-life septa are specially formed for extended use,

2013/05/09 · Trouble with old GC septa and columns. I used new septa and column out of the shelf for the Leco Pegasus III with Aijiren GC but got into trouble after about 20 injections. Split/Spitless injector Septa cracked and blocked the column and injector and I had to clean the injector. There are another new pair of septa and column.

Endura-Seals are the CRS 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. The duckbill valve in the Endura-Seal is much more resilient to needle wear and tear than the traditional pierced septa.
