Baseline drift
Thread Content
What is the cause of baseline drift and how to solve it?
Possible reasons: The temperature of the detector is too high and needs to be lowered appropriately.

1 It may be column loss or contamination. You can replace the substrate, or remove one or two circles at the column inlet. 2 Inlet port contamination, clean the inlet port. 3 Inlet port septum flow.
This is explained in the instrument manual. You should read the manual carefully.
If it is caused by external interference, you should find the reason yourself.
Air leakage, carrier gas flow rate imbalance, inlet contamination, impure carrier gas, etc. can all cause baseline drift and should be investigated one by one.
