Abstract
A novel high-performance liquid chromatography (HPLC) sample clean-up procedure for use in mass fragmentographic assays of (sub)-nanogram amounts of drugs in human plasma is described and compared with a conventional extraction sequence for sample purificaiton. With the assay of the new antidepressant drug mianserin hydrochloride (Org GB 94) as an example, the HPLC procedure is discussed with respect to retention time, recovery, purification, colum deterioration and convenience. It is demonstrated that HPLC sample clean-up is a useful and time-saving procedure for routine clinical analyses.
