Calibration curves were run by injecting variable concentrations
of BaA, Chry, BbF and BaP in acetonitrile-SUPRAS (9.1:90.9 v/v) (see
Section 2.1). Analytes in samples were analysed in pure SUPRAS.
No differences in retention times or peak areas were observed for
analytes injected in both types of solutions.
Calibration parameters and detection (MDLs) and quantitation
(QMLs) limits for the determination of PAHs by the proposed
method are shown in Table 3. The linear range was confirmed by
