A proposed reference method for the determination of dibenzofuran and dibenzo-p-dioxin in defoamers / by C.E. Luthe, R.H. Voss, H.B. Lee, and T.E. Peart.: En13-5/90-130E-PDF
"Based on a method developed by the Pulp and Paper Research Institute of Canada, a procedure optimized for the determination of dibenzofuran (DBF) and dibenzo-p-dioxin (DBD) in defoamers at low ng/g levels is presented. The defoamer is steam extracted and the extract in iso-octane is cleaned up on a basic alumina column. Final analysis is performed by GC-MS in the selected ion monitoring mode and the extraction recoveries of native DBD and DBF are monitored by using DBF-d8 and DBD-d8 as surrogates. Confirmation of DBD and DBF was done by comparing the ratio of peak areas for the quantitation and confirmation ions of each compound in the standard and the sample. Based on a 5 g sample and a final volume of 0.5 mL, the method detection limit is 1 ng/g for both DBF and DBD"--Abstract.
