title: Application of packed column supercritical fluid chromatography to the analysis of barbiturates.
abstract: The analysis of barbiturates using packed column supercritical fluid chromatography (SFC) has been investigated. The separations were carried out on either an ODS bonded silica or polystyrene-divinylbenzene polymer column with carbon dioxide as the mobile phase and flame ionisation detection. All the barbiturates were strongly adsorbed on the ODS-silica column, but reasonable separations were obtained by using the polymer column.
