WebMar 10, 2024 · Peak fronting occurs when an asymmetric peak is broader in the first half and narrower in the second half. Several factors may cause peak fronting including poor sample solubility, column collapse, or saturation/overload of the column. If the sample has poor solubility, it cannot be evenly dissolved into the mobile phase.
