In this article, we review stationary phase‐assisted sample prefractionation in proteomic analysis in 2019–2022 period. Applications are grouped according to the mode of retention used in the prefractionation step prior to the final analysis by low‐pH reversed‐phase liquid chromatography‐tandem mass spectrometry. Online or offline instrumental configurations are also commented on, with a highlight on novel online platforms. From the articles reviewed in this period, the order of popularity of chromatographic modes for sample fractionation is affinity chromatography > size exclusion chromatography > hydrophilic interaction chromatography > high‐pH reversed‐phase liquid chromatography > ion exchange chromatography.
