Gas Chromatography GC Troubleshooting Guide
Introducing our Gas Chromatography Troubleshooting Guide – your go-to resource for resolving challenges and optimizing performance in gas chromatography analysis.
Indications of errors with the system or method?
- Changes in peak shape/height (different than what was expected/known)
- Changes in retention time (other than expected change from cutting column during installation)
- Instability of the baseline
- Asymmetrical peak shapes, non-Gausian
- Any unusual behavior of expected peaks
Top Tips to Restore your Chromatography:
1. Split peaks (multiple peaks corresponding to a single compound)
2. Peak tailing
3. Peak fronting
4.Peak broadening/Poor resolution
5. Appearance of ghost peaks
6. Long solvent peak tail
7. No sample peak/Low response
8. Extreme baseline increase during temperature programming
9. High boiling compound not eluting (C60 to C80)
