综述了一种以细纤维填充针为萃取介质的小型化样品制备技术，特别是它在挥发性有机化合物气相色谱分析中的应用。当针纵向装入一束细丝(12微米直径)时。在样品表面也涂覆了聚合物材料，成功地实现了样品的预富集。通过在纤维填充针中的萃取过程中引入同时的衍生化反应，也提高了灵敏度。针的储存性能清楚地表明了该技术在环境分析过程中进行典型现场采样的潜力。在这篇简短的综述中，总结了作者开发的纤维填充提取针以及使用纤维填充针作为小型化提取装置的应用。
A miniaturized sample preparation technique that uses a fine-fiber-packed needle as the extraction medium is reviewed, especially in relation to its application to the analysis of volatile organic compounds by gas chromatography. When the needle was packed longitudinally with a bundle of fine filaments (12 µm o.d.) which were also surface-coated with polymeric materials, successful sample preconcentration was obtained. Improved sensitivity was also established by introducing simultaneous derivatization reactions into the extraction process in the fiber-packed needle. The storage performance of the needle clearly demonstrated the potential of the technique for typical on-site sampling during environmental analysis. In this short review, the fiber-packed extraction needle developed by the authors is summarized along with applications that use the fiber-packed needle as a miniaturized extraction device.
