Abstract

The paper reports a micro-chip with nano-pore channels integrated in a micro-channel as reservoir for quickly extracting analyt from aqueous solution to water-soluble organic solvents. Using this novel technology, trace-level residual of organophosphorus pesticide in water-solution can be micro-extracted to a common organic-solvent (e.g., ethanol) for subsequent analysis by GC-MS (Gas Chromatography-Mass Spectrometry).
