Reverse-phase chromatography

Separation on a non-polar stationary phase, typically C18-bonded silica, with a polar mobile phase. Retains by hydrophobic interaction.

Related terms

HILIC
Hydrophilic-interaction liquid chromatography. Polar stationary phase, high-organic mobile phase. Retains polar analytes that reverse phase cannot hold.
C18
Octadecyl-bonded silica: the standard reverse-phase stationary phase for peptides. Retention scales with the analyte's exposed hydrophobic surface, not with its mass.
