At present an estimated number of 600 RPLC columns are available on the market. A substantial number of these columns are nominally identical by possessing the same type of ligand e.g. C-8 or C-18 bonded to a substrate. But even nominally identical RPLC phases may show very different retention and selectivity properties.
This chapter compares about fifty RPLC columns, all packed with approximately 5 μm packing material that we have tested following an extended in-house testing protocol.
The columns were tested using neutral, acidic, basic and other test analytes at different eluent pH’s.
The aim of this chapter is to serve as a comparison guide for column selection to help you in identifying the optimal RPLC column for a specific separation.
