The method presented here, which uses a novel needle trap device (NTD) with sol-gel PEG-coated fibers in conjunction with GC, is a simple, inexpensive, and accurate tool for the analysis of trace levels of PCBs in water samples.

A GC–MS method, coupled with magnetic SPE with multi-walled carbon-nanotube (MWCNT)-coated iron oxide as the adsorbent, was developed for analyzing organophosphate esters in environmental water samples.

A method based on GC–MS coupled with magnetic SPE with multi-walled carbon-nanotube-coated Fe3O4 as adsorbent was developed for the analysis of four organophosphate esters (OPEs) in ambient water samples. The method was validated for its comparable sensitivity and potential application prospect.
