摘要

本文报道了一种集成了纳米孔通道的微芯片作为储层，可将分析物从水溶液中快速提取到水溶性有机溶剂中。利用该新技术，可以将水溶液中痕量有机磷农药残留微量提取到常见的有机溶剂(如乙醇)中，随后进行GC-MS(气相色谱-质谱)分析。

Mesoporous-silica nano-channels integrated in micro-fluidic chip for fast liquid micro-extraction of pesticide residual

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).
