I want to share some of the most common issues that we see with peak shapes in Gas Chromatography in the hope that if you spot some of these in your own work, you may be able to intercept problems and deal with them more effectively. Example 1 – Peak Tailing. Figure 1: Chromatograms showing worsening peak tailing effects.

Feb 28, 2021 · 4. Gas flow: a. An incorrect gas flow could be detrimental to the peak shape, where the wrong flow can result in broadened peaks. Verify the inlet and detector flow rates and adjust accordingly. Also verify the make-up gas flow and adjust. Splitting Peaks 1. Injector: a.

Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).
