title: On-line diode array UV-visible spectrometry in screening for drugs and drug metabolites by high-performance liquid chromatography.
abstract: The direct coupling of a multi-channel diode array UV-visible spectrophotometer to a powerful reversed-phase HPLC separation system is considered, especially for use in qualitative analysis, e.g., screening/identification of drugs and drug metabolites. The approach is illustrated by the screening for metabolites of butoprozine and ticlopidine directly in human and rat bile.
