Septa

Septum fås i forskellige materialer og tykkelser. PTFE/naturligt gummi er moderat prissatte tætninger til GC og HPLC med gode kemiske egenskaber. De er ideelle til flere injektioner på grund af høj resealability, men ikke så lette at penetrere som PTFE/RR. PTFE/high performance gummi er et meget rent syntetisk rødt gummiseptum, der giver reduceret baggrundsniveau til specifikke GC-applikationer med følsomme detektorer som ECD eller NPD. PTFE/silikone (T/S) septa er af høj kvalitet, lav baggrund og består af 100 % syntetisk rent silikone.
