GcSense-Crude Ar


*GcSense scalable architecture

Relying on its compactness, well-thought architecture and powerful embedded software, the GcSense can be offered in many other configurations. The GcSense chassis can fit up to 4 ovens, columns and valves and therefore can cover a vast range of applications

Enhanced plasma discharge (Epd) technology

The Enhanced plasma discharge technology brings two dispruptive advancements to the previous and well-known technology (PED).

First, two stabilising/focusing electrodes* have been introduced in the design to resolve plasma source instability (quenching and filamentary oscillation) and hence signal to noise improvement at low concentration.

Second, the electron injection electrodes* improve ionisation efficiency.
