GC Troubleshooting—Split Peaks

Split peaks can show up in gas chromatography when our injection isn’t working right or things aren’t transferring from the inlet to the column correctly. When troubleshooting split peaks, we should pay attention to our inlet configuration and setup, and we should confirm that everything with the injection is working correctly. We also want to make sure we’ve chosen a column stationary phase and solvent that are compatible with one another.
