Determination of Polyphenylarenes and Polynuclear Aromatic Hydrocarbons by Reversed Phase HPLC |
| |
Abstract: | Abstract Standard mixtures of polycyclic compounds are analyzed by reversed phase microcapillary liquid chromatography. Acetonitrile/water and acetonitrile/THF/water are employed as stationary phases, and capacity ratios are reported. Polyphenylarenes can be distinguished from polynuclear aromatic hydrocarbons by a large shift in capacity ratios when changing the mobile phase. The shift in capacity ratios is most significant for 1,3,5-triphenylbenzene, which is demonstrated by a gradient elution. The influence of THF and water on retention behaviour of solutes is described. |
