title: Automated sequential process for preparing samples for analysis by high-performance liquid chromatography.
abstract: A new method for the preparation of biological samples prior to high-performance liquid chromatographic analysis is described. The automated technique combines dialysis and trace enrichment. In order to investigate its potential, it has been applied to the estimation of total anticonvulsants and theophylline in serum.
