Complex samples well resolved, for reliable identifications. Low bleed baselines help ensure accurate quantification. Brominated flame retardants (BFRs) are widely used but potentially harmful materials currently being monitored in the environment. Analysis of higher molecular weight polybrominated diphenyl ethers (PBDEs) can present a particular problem: relatively high temperatures are required to elute them from a GC column, but they are easily debrominated at elevated temperatures. Poor peak shapes and extraneous peaks from breakdown products can complicate the analysis. Therefore, several key parameters must be optimized to ensure proper analysis of these compounds.
