Solid-phase microextraction (SPME) is a simple, efficient, sensitive, rapid and solvent-free sample preparation technique usually carries out on a coated fiber [1]. SPME commercial fibers offer a few drawbacks such as short lifetime, fragility of the fibers, bending of the needle, stripping of coatings, the poor reproducibility of the fibers and expensive cost [2]. Therefore developing stable, non-fragile and low-cost SPME fibers with easy preparation process and higher potential is necessary. In this work, a novel coiled-SPME fiber based on a stable, long life, low-cost and flexible resistance alloy is investigated for the first time. The quick-designed extraction fibers showed a unique ability to adsorption of PAHs analytes Soil and powerhouse and therefore were employed without any pre-treatment and special coatings.
