ECD Overview . 131
NOTE: Because an ECD is extremely sensitive, contamination from any part of the system can add to the
background and noise. To help assure a clean system the injector and detector should be baked-out and
both packed and capillary columns thoroughly conditioned before use. When conditioning columns for use
with an ECD, DO NOT attach the column to the ECD. Clean tubing and pure filtered gases should be used.
Whenever a column is disconnected from an ECD, the ECD should first be cooled to avoid oxidation of the
Nickel foil.
Vent the ECD Outlet
NOTE: If venting the ECD effluent is required, attach an additional piece of tubing to the tubing that is connected
to the ECD outlet. This does not affect the performance of the ECD.
1. Open the detector cover (see the following figure) to expose the top of the ECD.
2. Remove the two screws that secure the insulating cover to the Clarus GC.
3. Remove the insulating cover and detector cap.
This exposes the ECD outlet (see the following figure).
4. Attach the outer metal sleeve of the vent tubing (P/N N6100161) to the ECD Outlet.
5. Press down and turn the metal sleeve on the end of the vent tubing to
secure it to the ECD.
6. Thread the vent tubing through the detector cap and insulating cover as you position them over
the ECD.
