We had a H2O leak of 17% and our carrier gas filter was saturated with moisture. At this time, N2 and O2 levels were both well below 5%.
We had a N2 leak after replacing the saturated filter with a new Gas Clean Filter (H2O and O2 levels were <5%). We followed the instructions, entered the split flow to 400 mL/min to purge the filter. The N2 level significantly dropped to <5%, however, after we return to splitless mode the N2 levels creep back up to ~40% and remains there. We have purged multiple times and the same situation occurs. The only change we made was replacing the new filter- nothing else was touched.
Has anyone experienced this before and can you offer any solutions, please?
Thank you for your help
