Peak fronting can occur when one or more of the compounds injected on the column exceeds the capacity of the liquid phase of the column. The thinner the liquid-phase film, the less of each compound can be retained by the column. To prevent fronting, reduce the injection volume, increase the split ratio, or inject a less concentrated sample.
