Abstract: | 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. |
