Identification of emerging iodinated disinfection by-products (DBPs) in water is difficult due to matrix complexity and low concentrations of these compounds. Analytical techniques are required with high resolution, high mass accuracy and sensitivity. 

In this work, a novel gas chromatography (GC), coupled with high-resolution accurate mass Orbitrap mass spectrometer (the Thermo Scientific™ Q Exactive™ GC hybrid quadrupole-Orbitrap mass spectrometer), has been used for iodo-DBPs detection and accurate mass identification in chlorinated and chloraminated water samples.
