Abstract:
An analytical method based on ultra performance liquid chromatography (UPLC) coupled with a photodiode array (PDA) detector has been developed for the simultaneous determination of 16 polycyclic aromatic hydrocarbons (PAHs). The comparison of UPLC and the conventional high performance liquid chromatography (HPLC) has been carried out. The major advantages of UPLC over HPLC include the faster analysis speed, considerably increased sensitivity and significantly improved detection limit. By UPLC, the whole analytical process can be performed in 13.5 min and the limits of detection for the 16 PAHs were between 2 pg and 20 pg.
