There are many factors that influence the performance of a high performance liquid chromatography (HPLC) stationary phase, of which the chemical nature of the bonded phase ligand is important, but by no means all encompassing. Minor manufacturing parameters such as the method of electropolishing the internal surface of the column can also have an effect on the selectivity and efficiency produced by a particular column.
