摘要
The sample solvent has a significant effect on band profiles in preparative liquid chromatography. This effect has been described by Guiochon and Jandera in non-aqueous reversed-phase high-performance liquid chromatography. Similar behaviour was observed in hydrophobic interaction chromatography of cytochrome c and lysozyme under conditions of column overloading. If the sample solvent contains a lower concentration of salt than the starting mobile phase in gradient hydrophobic interaction chromatography, the protein peak will be broken to two peaks. One peak is longer-retarded, another is shorter-retarded by hydrophobic interaction. The latter changes its retention time with the different injection volumes. This results in a loss in the recovery of protein in preparative chromatography. The possible mechanism of the band-splitting was investigated.
