Analysts from the Department of Analytical Chemistry at the University of Cordoba (Cordoba, Spain) used ionic liquid-based, single-drop microextraction followed by gas chromatography with mass spectrometric detection to analyze benzene, toluene, ethylbenzene, and xylene isomers (BTEX) in water.
Analysts from the Department of Analytical Chemistry at the University of Cordoba (Cordoba, Spain) used ionic liquid-based, single-drop microextraction followed by gas chromatography with mass spectrometric detection to analyze benzene, toluene, ethylbenzene, and xylene isomers (BTEX) in water. The ionic extraction liquid, 1-methyl-3-octyl-imidazolium hexafluorophosphate, has a high affinity for the aromatic analytes but is immiscible with water. Repeatability (RSD) for the method reportedly ranged from 3.0% for o-xylene to 5.2% for toluene.
