Replacing the make-up gas adapter (GC-ECD)
The make-up gas adapter consists of a line from the detector pneumatics manifold that carries make-up gas to a weldment that screws into the bottom of the ECD detector.
When re-installing the make-up gas adapter, ensure the following:
• Approximately six inches of the make-up gas line should reside in the oven after installation.
• The make-up gas line should be bent into a coil that loops around the bottom of the detector weldment and make-up gas adapter.
Tip: There are two pneumatics blocks on the EPC version of the ECD pneumatics manifold. The outside block is the anode purge gas line and the inside block is the make-up gas line.
