With a 10 µm Particle, this column works well with higher flow rates and lower back pressures. Used for very hydrophobic or neutral compounds in Reversed Phase, this Butyl Phase is excellent for preparative HPLC for small molecule purification. Expect Less retention than with a C18 column but more than with a C8.
