A method of coating at least one silica capillary using a novel dual ligand sol-gel sorbent and method of manufacture of such sorbent is provided herein. The dual ligand sol-gel sorbent provides superior enrichment effects through simultaneous exploitation of superhydrophobicity of one of the ligands and the ability of the other ligand to undergo Ï-Ï interaction with hydrophobic aromatic analytes. Sorbent performance is enhanced both in terms of analyte enrichment and sorbent stability, such as pH stability and solvent stability.
