Septum

Septum je k dispozici v různých materiálech a tloušťkách. PTFE/přírodní kaučuk jsou cenově dostupná těsnění pro GC a HPLC s dobrými chemickými vlastnostmi. Jsou ideální pro vícenásobné injekce díky vysoké schopnosti opětovného utěsnění, ale nejsou tak snadno prostupná jako PTFE/RR. PTFE/vysoce výkonná pryž je vysoce čisté syntetické červené pryžové septum, které poskytuje sníženou úroveň pozadí pro specifické aplikace GC s použitím citlivých detektorů, jako je ECD nebo NPD. PTFE/silikonová septa (T/S) jsou 100% syntetická, vysoce čistá silikonová septa s vysokou kvalitou a nízkým šumem/blank hodnotou.
