“…Bolt et al (1997) observed instability of deuterium labelled PAHs due to the loss of deuterium from the labelled compounds. Carbon-13 labelled compounds are therefore External standards of all the compounds in solvent were used for the determination of the calibration curves, using the approximate concentrations of 0 µg [Insert Figure 2 here]…”

Analysis of polycyclic aromatic hydrocarbons in vegetable oils combining gel permeation chromatography with solid phase extraction cleanup. Food Additives and Contaminants, 2007, 24 (07) DK-8520 Lystrup, Denmark AbstractA semi-automatic method for the determination of polycyclic aromatic hydrocarbons in edible oils using a combined Gel Permeation Chromatography/Solid Phase Extraction (GPC/SPE) clean-up is presented. The method takes advantage of automatic injections using a Gilson ASPEC XL sample handling system equipped with a GPC column (S-X3) and pre-packed silica SPE columns for the subsequent clean-up and finally gas chromatography-mass spectrometry (GC-MS) determination.
