Why Trajan?
Trajan have developed unique technologies in the course of developing injection port septa for gas chromatographs.
Even if carrier gas is of the highest quality, contaminants can be picked up from every part of the gas line – a gas filter is, therefore, needed to ensure that maximum productivity is achieved.
As a result, CRS GC septa are pre-conditioned for low bleed, plasma-coated to reduce sticking and are packed in blister packs and glass jars for high purity.
