Note 40Comparison of Septa by Direct Thermal Extraction

Septa from 5 different manufacturers (HP,SGE,J&W,Restek and Supelco) were analyzed by "Direct Thermal Extraction" to identify and compare the volatile organics present. A series of studies were conducted to examine which septa had the lowest amount of bleed and which were the most suitable type of septa commercially available.

Column Bleed & Septa Bleed-Same Old Thing

Dec 10,2013· On a seminar trip I was confronted with describing why septa bleed and column bleed are different. My canned answer is that septa bleed has a base peak of m/z 73 and column bleed has a base peak of m/z 207 and we can prove this with a GC-MS. Keep in mind that both column bleed and septa bleed are made up of cylic siloxanes which begs the question of what makes them different.
