To troubleshot this problem, first, I checked the cloggage on solvent inline filters which are fine, then columns, lines by disconnecting them from downstream direction, but the pressure still increased at over 400 bars even I disconnected everything downstream from the pump head and let the purge valve open.
Does anyone experience this same issue before and can someone give suggestions what are the possible causes? Thanks a lot!
