Troubleshooting GC peak shapes - Crawford Scientific
Figure 3: Subtle peak shape deformation that is known as Peak Fronting. In Figure 3 we again see two chromatograms which show a worsening degree of peak fronting (blue more pronounced than red). In many cases the cause of peak fronting is an overload of the GC column produced by the injection of too great a mass of analyte.
