SHARPER PEAK WITH UNIQUE FLOW PATH OPTIMISED FOR CAPILLARY COLUMN*

We have optimised our discharge cell for both packed and capillary columns. Due to the low carrier flow with capillary columns, internal volume and internal volume refresh rate is of outmost importance.

Our unique flow path design* uses a reverse doping flow to vent away column carrier gas from the discharge. Since the ionisation process is fast, the analytes that elute from the column have sufficient time to be ionised without stagnating into the plasma discharge. The result is sharper peak.

 

EASY INTEGRATION ON ANY LAB GC

As the SePdd is powered by our advanced CPM platform, it can easily be integrated to any GC platform. The chromatogram signals are available as analog outputs or for more advanced GC platform, in a digital format. Different mounting brackets can also be provided to accommodate your platform.
