Long Life GC Autosampler Septa are designed for use with GC Autosamplers. The 5, 9, 11 and 11.5 mm diameter Long Life septa are available with our unique prepierced center depression which guides the syringe needle to the same injection point, extending septa life and reducing needle.

Different septa material for LC and GC applications There are many different types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa When selecting which septa is right for your experiments, it
Probably the number one problem with GC injection port septa is coring, which is when a hole is produced in the septum when it is punctured by a syringe needle. In addition to causing poor chromatography, or loss of sample from the injection port, coring can cause unwanted and unknown (ghost) peaks in the chromatogram.
A GC septum is located at the top of the injection port and serves two functions: 1) providing a leak-free seal to maintain carrier gas pressure inside the system 2) handling repeated puncturing by a syringe needle for sample introduction purposes without severe coring or leaking.
General Purpose Septa for GC Aijiren’s general-purpose septa are made from an enhanced injection-molded silicone rubber material. The septa material, dark red or gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C.
Aijiren's premium septa also have a recess on the injection side, to guide the syringe needle to the same point with every injection.
