Novel cationic surfactant ion pair based solid phase microextraction fiber for nano-level analysis of BTEX

▶ Novel application for surfactants in construction of GC-SPME fibers. ▶ Separation of xylene isomers together with other compounds by low detection limits for all compounds (for Nano-level BTEXs compound analysis). ▶ Low detection limits, wide linear dynamic ranges, good reproducibility, high fiber capacity and high mechanical durability are some of the most important advantages of the new fiber. ▶ Surfactant applications in separation sciences and hazard material determinations.
