Reversed Phase HPLC Columns - ODS (C18)

Reversed phase HPLC has a non-polar stationary phase and an aqueous, moderately polar mobile phase. With these stationary phases, retention time is longer for molecules which are more non-polar, while polar molecules elute more readily. Octadecylsilane (ODS), C18, is the most popular reversed phase technique used today.
