Utilisation of GCxGC.TOFMS as a Broad-Spectrum Analysis for Endocrine Disruptor Compounds in Urban and Rural Watersheds

摘要

In conclusion, comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry was utilised in this research to detect endocrine disruptors, personal care products, as well as other pollutants in samples obtained from urban and rural point sources along a Midwestern watershed. A solid phase extraction method was developed using a hydrophilic modified styrene based polymer for a broad range of compounds from aqueous samples. An optimised GCxGC method was developed using a conventional non-polar and mid-polarity column set.
