The application of hybrid mass spectrometry/mass spectrometry and high-resolution mass spectrometry to the analysis of fish samples for polychlorinated dibenzo-p-dioxins and dibenzofurans.

Abstract

A hybrid mass spectrometer operated in low-resolution selected decomposition monitoring (SDM) mode was used for the analysis of whole fish samples for the 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and poly-chlorinated dibenzofurans (PCDD/Fs). These fish samples were previously analyzed for PCDD/Fs using a high-resolution mass spectrometer following EPA protocols. The hybrid tandem mass spectrometric method using loss of COCl gave similar quantification results to those obtained by high-resolution mass spectrometry and eliminated the interferences attributed to polychlorinated biphenyls that were encountered in the high-resolution mass spectrometric analysis. Comparison of the two methods shows that the high-resolution mass spectrometric method surpasses the tandem mass spectrometric method in other analytical figures of merit, such as detection limit, linearity and reproducibility.
