Description:
Multiple carbon-13 internal standards improve the precision and accuracy of the mass spectrometric analysis of polychlorinatedbiphenyl (PCB) congeners compared to analyses using a single carbon-13 internal standard. The mean percentage error in PCB congener analysis on the micrograms g-1 level using multiple ion detection and three carbon-13 internal standards was 6.29 percent. This precision in single laboratory work suggests that the method will be useful for interlaboratory studies monitoring PCB residues and contaminants of public health significance.
