Prediction of gas chromatographic separation for PBDE congeners from
molecular descriptors

Abstract
Polybrominated diphenyl ethers (PBDE) have been identified as environmental
contaminants with a widespread distribution. The separation properties of PBDEs
in high-resolution gas chromatography (HRGC) are important both for
environmental analysis and for determining physical properties such as the
vapour pressures. This study reports a quantitative structure-property
relationship (QSPR), established between relative retention times on capillary
HRGC and two constitutional structure descriptors that can perform equally well
as more elaborate approaches. The simplified approach is recommended for
explanatory models, while a more in-depth multivariate characterisation is
suggested to assure similarity in applying prediction models.
