abstract

  • Although various investigators have studied the possible use of gas chromatography for separating polycyclic aromatic hydrocarbons, only partial success in resolving the important benzpyrene fraction has been achieved. This study employed gas-solid chromatography with inorganic salts as the stationary phases. The performance of these salt packings is affected by the solid support. Pink diatomaceous earth type of supports produced longer retention times but better resolution of the polycyclic hydrocarbons. Certain compound pairs, previously unresolved by paper and thin-layer techniques, can now be completely separated. Furthermore, the resolution of the benzpyrene fraction, while incomplete, shows improvement over that obtained with organic liquid stationary phases. These separations arise from weak bonding forces between the salt-modified solid support and the polycyclic hydrocarbons, resulting in alterations of the elution order usually observed with organic liquid stationary phases. Slight variations in the elution order are also observed when changing from one salt to another. © 1969 Oxford University Press.
