Monitoring disinfection by-products in water using thin-film SPME coupled with GCxGC and BenchTOF MS Thin-film solid-phase microextraction (TF-SPME) with comprehensive two-dimensional gas chromatography and BenchTOF™ time-of-flightmass spectrometry (GCxGC–TOF MS) provides efficient non-target screening of organic pollutants in water. Water samples were analysed by GCxGC–TOF MS before, during and after treatment with a water purification system, and compositional differences were uncovered using automated, non-target workflows in ChromCompare+ software.
