| Abstract: | Mass spectrometry/mass spectrometry (MS/MS) has been demonstrated to be a valuable technique in the analysis of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs, PCDFs). In this study, we demonstrate both the value and limitations of high-resolution mass spectrometry (HRMS) and MS/MS in the analysis of PCDDs and PCDFs. We have found that in certain cases, MS/MS can solve analytical problems that cannot be solved by high-resolution mass spectrometry and we demonstrate the reliability and reproducibility of MS/MS in the analysis of PCDDs and PCDFs in environmental matrices. |
