Performance of palm fibers as stationary phase for capillary gas chromatographic separations.

Herein we report the first example of exploring bio-based materials, palm fibers (PFs), as a stationary phase for capillary gas chromatographic separations. The PFs capillary column was fabricated by the sol-gel coating method and showed a weak polar nature and high column efficiency over 4699 plates per m for n -dodecane, naphthalene and n -octanol. Importantly, the column exhibited high selectivity and resolving capability for more than a dozen mixtures covering a wide-ranging variety of analytes and isomers. In addition, it was applied for the determination of isomer impurities in real samples, proving its good potential for practical gas chromatographic analysis.
