A novel, simple, and efficient sample preparation method was developed for microextraction
of benzene, toluene, ethylbenzene, and xylene (BTEX) from water samples before gas …

Liquid-phase microextraction (LPME) based on solidification of a floating organic micro drop
followed by gas chromatography (flame ionization detection) to pre-concentrate and …

We have developed a modified method for the extraction and preconcentration of benzene,
