Monitoring disinfection by-products in water using thin-film SPME with GC×GC–TOF

Originally presented at the 19th International GC×GC Symposium in 2022  

The poster entitled “Monitoring disinfection by-products in water using thin-film SPME with GC×GC–TOF MS” was presented by SepSolve Analytical at the 19th International GC×GC Symposium, which was held on 29 May–2 June 2022 as a virtual event.  

Efficient non-target screening of water samples

Water pollution can occur when harmful substances contaminate streams, rivers, lakes or other bodies of water. Different processes are used for removing these substances from water including disinfection. Halogenated disinfection by-products are often formed as a result, and these are being investigated to understand their effect on human health.  

This poster demonstrates how thin-film solid-phase microextraction (TF-SPME) with comprehensive two-dimensional gas chromatography and BenchTOF time-of-flightmass spectrometry (GC×GC–TOF MS) provides efficient non-target screening of organic pollutants in water. Water samples were analysed before, during and after treatment with a water purification system to determine compositional differences.
