GC Septa | Laboratory | Hamilton Company Laboratory GC Septa Three Layer GC Septa Three Layer Septa is made of preconditioned silicone rubber and is 3.81 mm (0.150 in) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 200° C. High Temperature GC Septa

aggressive solvents. The thin membrane allows for penetration by most normal gauge metal HPLC needles. PTFE septa are not resealable and should not be used with highly volatile solvents, short cycle times or multiple injection methods. PTFE septa are rarely used for GC applications. Polyethylene (PE) Septa and Integral Molded Closures

All GC septa, regardless of their composition, puncturability, or resistance to thermal degradation, will be a source of problems if they are mishandled. Always use clean forceps, or wear clean powderless or cotton gloves when handling septa. Do not handle them with bare fingers or with powdered latex gloves—contaminants such as finger oils

PTFE/silicone septa are always best. What force is required to penetrate the septum? Generally, silicone septa are more easily pierced than red rubber or butyl septa. For thicker, hard-to-pierce septa, a small gauge (23 gauge) needle may be required, or a stronger S-needle can be used. Preslit septa are the best option for

Advanced Green inlet septa eliminate sticking and reduce coring. 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, meaning less downtime.

T/S/T septa provide superior performance with Aijiren 1050, 1090 or any autosampler employing a large diameter, blunt tip needle. PTFE Septa A solid disk of 0.010” thick PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for easy penetration by most needles. PTFE septa are not resealable.

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.

Jul 10, 2012 · GC–MS chromatograms obtained using Septum A at different IP temperatures. The other three septa (B, C and D) were also tested separately in a similar manner, and their respective chromatograms are compared with that of Septum A in Figures 4 A–4D at fixed injection port temperatures 100, 150, 200 and 250°C.
