The effects of concentration and weight\u2010average molecular weight (Mw) of PVP, solvent viscosity, solvent polarity, and sample temperature on the resolution of these components were investigated. It was found that both higher PVP concentration and higher PVP Mw caused the increase of diffusion resolution for the three components. Moreover, the diffusion resolution did not change at viscosity\u2010higher solvents. Moreover, the three components showed different resolution at different solvents. As temperature increased, the diffusion resolution between <jats:italic>p<\/jats:italic>\u2010xylene and benzyl alcohol gradually increased, and the one between <jats:italic>p<\/jats:italic>\u2010xylene and <jats:italic>p<\/jats:italic>\u2010methylphenol slightly increased from 278 to 298\u2009K and then decreased above 298\u2009K. It was also found that the polarity of the analytes played an important role for the separation by affecting the diffusion coefficient.
