GC 7890B septum purged remains 0.1 while it is set to 3.0 mL/min.

It seems, the outlet line of septum purg closed by liquids. Or the line closed in the end of line. Please check it.

And in acquisition software, you cal increase the flow of septum purge from 3 to 6 or opper to push the liquid for going out. Or by a hair heater warm the line for many times to going out the liquids.

There should be no liquid in the septum purge line. Pushing any possible liquid out of that line into the electronic pressure control (EPC) module using pressure will more than likely permanently damage it. Trying to warm up that line to drive any possible residue out of it would drive it into the EPC module and more than likely permanently damage it.

Thanks for your response. I will clean everything.
