Gas chromatography solvents
WebTailing doesn’t always have to be so subtle and I’ve shown below an extreme example where solvent peaks (present in the sample at trace levels) show very bad peak tailing. Figure 2: Pronounced peak tailing in a residual solvents GC method. This example highlights a good tip when troubleshooting tailing peaks.
