Thermo Fisher Scientific has released the TR-Green Injection Port Septa, which are individually moulded for an exact fit in the GC inlet.
The materials and process parameters used ensure a true low-bleed green septum.
They feature an extended life-span, minimal coring and reduced stickiness, which decrease the risk of contamination and ensure optimised results.
Each batch of TR-Green Septa is subjected to a range of QC processes: a bleed test for low contamination; a stick test for low injection port adhesion; and a stable durometer test for consistent use.
A small Centerguide dimple designed to minimise contamination directs the needle into the same spot every time.
The formation of only one channel path reduces the possibility of any coring from the disruption of contiguous needle channels.
This dimple facilitates low bleeds as core production is minimal, removing the chance of them being pushed into the liner.
As a key component of sample introduction, the TR-Green Septa have a life span of hundreds of injections and maintain an air-tight, leak-free seal for optimised GC performance.
