Remove the end section of the column. Carrier gas cylinder pressure too low to allow control. Replace the carrier gas cylinder. Increase the pressure. Drifting carrier gas or combustion gas flows. Check the gas controllers. Accumulation of impurities in the column. Check impurity levels in the gas source.

Here are some common issues in gas chromatography and their possible solutions: 1. Baseline instability or Drift in Gas Chromatograph. Possible causes: Column bleed, contamination, or detector instability. Solutions: Bake-out the column at a higher temperature, replace the column if necessary, ensure proper sample preparation and injection ...

Perform method at higher temperature if possible. Activated injector port surface is causing adsorption of certain compounds. Replace septum, inlet liner, and/or gold seal. Perform full injector port maintenance. Compound is too active for gas chromatography. Chemically derivatize compound if possible.

Understanding the chemistry behind gas chromatography (GC) separations can lead to faster problem identification and improved troubleshooting. Fortunately, sudden selectivity changes in GC are fewer than in other forms of chromatography — it's not as if we can make up the eluent with the incorrect amount of organic or at the wrong pH after all!
