Monofluorinated analogues of polybrominated diphenylethers (F-PBDEs) - standards for analysis: retention behaviour in gas chromatography

Retention-time database of 126 polybrominated diphenyl ether congeners and two bromkal technical mixtures on seven capillary gas chromatographic columns.

The elution order of 126 polybrominated diphenyl ethers (PBDE) was determined for seven different gas chromatographic (GC) stationary phases. The resulting database facilitates selection of the most suitable GC columns for developing a quantitative, congener-specific BDE analysis and the testing of retention prediction algorithms based on structure relationships of GC phases and congener substi...

GC×GC–ToF MS FOR THE ANALYSIS OF ANTHROPOGENIC AND NATURALLY PRODUCED ORGANOBROMINATED COMPOUNDS

Introduction Comprehensive two-dimensional gas chromatography (GC×GC) has gradually been introduced to solve some separation problems found during the analysis with one-dimensional GC. The use of high speed time-of-flight mass spectrometry (HS-ToF MS) as a detector for GC×GC (GC×GC–ToF MS) adds an additional dimension to the analysis allowing unambiguous determination based on nominal mass. Thi...

Study of the retention behaviour of monofluorinated analogues of Polybrominated Diphenylethers (F-PBDEs) in gas chromatography

Introduction Polybrominated diphenyl ethers (PBDEs) are globally distributed in the environment. They have been used as flame retardants for over 2 decades [1]. PBDEs have been found to bioaccumulate and there is also a concern about the health effects of PBDE exposure due to their potential endocrine disrupting properties. PBDEs are structurally similar to polychlorinated biphenyls (PCBs) and ...

RP-HPTLC Retention Data in Correlation with the In-silico ADME Properties of a Series of s-triazine Derivatives

The properties relevant to pharmacokinetics and pharmacodynamics of four series of synthesized s-triazine derivatives have been studied by Quantitative structure-retention relationship (QSRR) approach. The chromatographic behavior of these compounds was investigated by using reversed-phase high performance thin-layer chromatography (RP-HPTLC). Chromatographic retention (RM0) was correlated with...
