Scientists from Xiamen University (Xiamen, China) employed solid-phase microextraction (SPME) with a carbon nanotube–coated fiber to analyze phenols in aqueous samples. The final analysis was performed using high performance liquid chromatography (HPLC) with UV absorbance detection. The fiber coating reportedly did not swell in organic solvents nor separate from the substrate, and it had high mechanical strength. They were able to perform more than 80 analyses using one fiber. Detection limits were 0.9–3.8 ng/mL, and recoveries from spiked seawater and tap water were 87.5–102%.
