title: High-performance liquid chromatography of antipyretics on chemically modified porous glass.
abstract: An octadecylsilyl porous glass was prepared and used as the packing for reversed-phase high-performance liquid chromatography. Five antipyretic drugs (aspirin, caffeine, guaiacol glycerol ether, 3-hydroxy-p-butyrophenetidine, and phenacetin) were separated in 2 min with a mobile phase of 20% acetonitrile at a flow-rate of 3.0 ml/min. A pharmaceutical preparation, containing aspirin, phenacetin, caffeine and chlorpheniramine maleate was analysed in 2 min with a mobile phase of acetonitrile-water-acetic acid (20:79:1). The packing seems promising for the rapid analysis of pharmaceuticals and biomedical compounds.
