Two-dimensional gas chromatography–time-of-flight mass spectrometry (GC×GC–TOF-MS) is a valuable analytical method for use with passive sampling techniques for the detection of pollutants in water. With this method, it is possible to separate components that would be coeluted in one-dimensional GC, resulting in improved confidence in identification of pollutants. The combination of passive sampling and TOF-MS ensures high sensitivity, and the information-rich datasets mean that the method can be applied to the detection of nontarget compounds with little additional effort.
