The influence of different factors on efficiency and peak asymmetry for a wide group of PAHs in micellar liquid chromatography (MLC) is studied. One can see that efficiency increases as the concentration of surfactant in the mobile phase increases. The addition of 2-propanol increases efficiency up to a 15%. The simultaneous effect of temperature and flow rate show the influence of hydrophobicity of solutes on efficiency. H-μ plots show a different behavior of PAHs in MLC as compared to RP-HPLC.
