Abstract
Overview
ISO 11423-2:1997 - "Water quality - Determination of benzene and some derivatives - Part 2: Method using extraction and gas chromatography" - specifies an extraction-based laboratory procedure for measuring benzene, toluene, ethylbenzene and xylenes (BTX) and similar nonpolar aromatic compounds in water and wastewater. The method combines liquid–liquid extraction (commonly with pentane) and analysis by gas chromatography (GC) using capillary columns and a flame ionization detector (FID). This part complements (head-space GC) and is chosen based on sample type and available instrumentation.
