Agilent GC Gold Seal Replacement | GC Inlet Maintenance

How to replace the gold seal on an Agilent 7890 GC inlet.

This video shows the hands-on process of removing the lower inlet hardware, replacing the gold seal, reassembling the inlet, and reinstalling the GC column.

For trace-level GC/MS analysis, inlet contamination and active surfaces can contribute to poor response, peak tailing, discrimination, elevated background, and failing CCVs. Gold seal replacement is an important part of maintaining a clean and inert GC inlet flow path.
