Shall we choose silica gel or alumina as stationary phase?

Silica gel and alumina are both polar adsorbents.In a typical column, the stationary phase, a solid adsorbent normally silica gel or alumina.

Silica is quite popular and widely used, but it is of slightly acidic, it will retain basic compounds, but alumina is the opposite.

So they are suitable for separating weakly or moderately polar components.
