Quantitative HPTLC in Assaying Body Fluids for Drugs and Metabolitess such as sensitivity. Commercially available instrumentation, e.g. for plate development in its different modes, is considered, and the optimization of a spotting device (see.); Examples of applications are given later (art. #D-5).

Taking Aliquots from Small Volumes of Upper Phasesanalyte completely from 2 ml of aqueous solution into 50 µl of isooctane; but to take an aliquot of the organic layer into a syringe for chromatography was troublesome. It was hardly possible to sample the organic phase without contaminating it with the aqueous phase.

Problems Arising from Assaying Low Concentrations by HPLC in train a number of problems; some are well known, others are not suspected by those workers who deal only with samples at high concentration. The examples given represent problems that have occurred in a drug metabolism bioanalytical laboratory. Readers may add to the list.

Extraction of Drugs and Metabolites from Plasma and Urinement of new extraction procedures for determining drugs and metabolites in biological fluids has been relatively neglected. Yet there have been advances in extraction procedures, and this article summarizes the options available and gives examples of their use. Deproteinization, solvent extraction a
