The separation of polynuclear aromatic hydrocarbons by gas chromatography was described.
The retention times of 14 kinds polynuclear aromatic hydrocarbons and methyl cholanthrene were measured on SE-30, SE-52, JXR, XE-60, cyclohexanedimethanol succinate (CHDMS) and neopentylglycol succinate (NGS) columns, and the operating conditions were investigated for the compounds which were difficult to be separated. Using a 2% SE-30 column at the column temperature of 90°C, phenanthrene and anthracene were separated almost satisfactorily.
The possibility of the use of inorganic material as a stationary phase was discussed. A mixture of lithium nitrate and SE-30 was found to be very satisfactory for the separation of polynuclear aromatic hydrocarbons.
