Also, polymerbased reversedphase columns generally tend to result in broader peaks than silicabased columns. This is particularly common for aromatic compounds in polystyrene columns. This is especially noticeable when using methanolbased mobile phases, whereas it is not very noticeable for acetonitrilebased mobile phases. Consequently, the latter is recommended for polymer reversed phase
