Comprehensive high-performance liquid chromatographic methodology for the determination of thiothixene in bulk drug, finished product, and dissolution testing samples.

abstract：:A column-switching high-performance liquid chromatographic assay combined with a heart-cutting technique and UV detection (LC/LC/UV) was developed to determine ceftibuten, a new oral cephalosporin, in human plasma. Plasma samples were directly injected into the first chromatographic column for sample cleanup and extra...
