Biomarker Focus 14:Polychlorinated biphenyls (PCBs)

Hovedbilde BMF 14 struktur BMF 14

Polychlorinated biphenyls (PCBs) have been the subject of a broad range of studies and investigations because of their environmental persistency and bioaccumulation. Their abundance as pollutants stems from their worldwide manufacture as heavy-used industrial chemicals, e.g. Aroclors with the main application as dielectric fluid in capacitors and transformators. PCBs are formed as mixtures by the addition of chlorine to biphenyl. PCB congeners can be classified as coplanar, dioxinlike with none or one orthosubstitution and nonplanar with substitutions in the ortho-positions. The coplaner PCBs shows a similar toxicity as the dibenzofurans and the dioxins.

 

F-PCBs®, An overview of advantages
F-PCBs® Fluorinated Internal Standards for PCB analysis
A flexible and cost-efficient alternative:

Mono- and difluorinated PCBs are closely similar to the parent PCBs in terms of physico-chemical properties, and are ideal internal or surrogate standards for GC-MS, GC-ECD, GC-FID and two-dimentional GC. The F-PCB® internal standards offered by Chiron have several advantages over the more traditionally used 13C isotopes and unlabelled internal standards:
° Cost efficient. Much cheaper than the 13C isotopes.
° Gives one single, pure isotope (F has only one isotope)
° Can be used with GC-ECD detection, 13C can not since they coelute with the native.
° Do not discriminate from the native upon work-up.
° “Designer retention times” (ortho-, meta-, para-F) possible for optimal elution rate.
