Gas chromatography of homologous esters

Relationship between gas chromatographic retention of polychlorinated dibenzofurans and calculated molecular surface area

“…The increase in retention of the PCDF's with the number of chlorine atoms (Figure 2) suggests that the PCDF isomer groups are chromatographically separated on the basis of solubility in the liquid phase. This is observed for homologous series (14)•, retention increases as the carbon number increases. As the number of carbon atoms increases in such a series there will be an increase in surface area and retention.…”
