The advantages of high mass resolving power (MRP) and mass measurement accuracy (MMA) combined with gas-phase ion-molecule reactions for highly confident identification of selected emerging contaminants in complex sample mixtures such as contaminated soils or water are demonstrated. The use of high performance mass spectrometers (e.g., FT-ICR MS or Orbitrap FTMS) combined with gas-phase ion molecule reactions and data reduction or visualization approaches such as Kendrick plot construction allow rapid identification of chlorinated contaminants (e.g., persistent organic pollutants (POP)) in complex environmental sample mixtures at the highest level of confidence currently achievable. Such methodologies avoid the need for pre separation of the sample (e.g., gas chromatography (GC) or high pressure liquid chromatography (HPLC)) and at the same time offer a suitable approach for highly reliable and rapid identification of contaminated areas.
