Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut SI is effective at separating compounds with very similar structures. Applying the analytes in a nonpolar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.
