Hello,
I am looking for some advice on how to troubleshoot a small air leak in a 7010 triple quad. The leak is small enough that using an an air can at several of the check points can't detect a leak. So far I changed the side plate o-rings, vent valve o-ring and reinstalled the column. We have a second GC-TQ that shares the same gas cylinders (although that one has a universal gas trap) which easily passes the air/water check, although the one GC-TQ in question just barely fails the nitrogen/oxygen criteria.
Any suggestions would be appreciated.
