摘要：

An analytical method is described for separating polyaromatic hydrocarbons using modified supercritical carbon dioxide and pure carbon dioxide. The effects of adding methanol in supercritical carbon dioxide mobile phase were studied. The modifier, methanol affected especially in the retentions of polyaromatic hydrocarbons.
