Optimisation and comparison of several microextraction/methylation methods for determining haloacetic acids in water using gas chromatography.

Abstract

This article presents the different modes and configurations of liquid-phase microextraction (LPME) through comparison with headspace solid-phase microextraction (HS-SPME) for the simultaneous extraction/methylation of the nine haloacetic acids (HAAs) found in water. This is the first analytical case reported of solvent bar extraction-preconcentration… (More)
