摘要：

Significant improvements in selectivity for amperometric detection in flow analysis are achieved at covalently modified glassy carbon electrodes. Flow detectors modified with p-alkylbenzene (alkyl = methyl, decyl) and p-phenylacetate monolayers demonstrate how selectivity may be obtained on the basis of solute hydrophobicity and charge. The modified electrodes are stable under hydrodynamic conditions and in aqueous and mixed aqueous/organic carrier streams.
