title: Retention characteristics of aromatic hydrocarbons on silica and aminopropyl-modified monolithic columns in normal-phase HPLC.
abstract: A suite of aromatic hydrocarbons were used to investigate the influence of structure upon retention in normal-phase HPLC mode using bare silica and aminopropyl-modified silica Chromolith type monolithic columns. The aminopropyl-modified silica monolith was used to separate a complex petroleum fraction based on double bond equivalence.
