✦ Synopsis

This reference examines innovations in separation science for improved sensitivity and cost-efficiency, increased speed, higher sample throughput and lower solvent consumption in the assessment, evaluation, and validation of emerging drug compounds. It investigates breakthroughs in sample pretreatment, HPLC, mass spectrometry, capillary electrophoresis and therapeutic drug monitoring for improved productivity, precision, and safety in clinical chemistry, biomedical analysis, and forensic research.From saliva, hair, and biological samples to illegal drugs and toxins, Separation Techniques in Clinical Chemistry is a thorough single-source guide for analytical, organic, pharmaceutical, medicinal, physical, surface, and colloid chemists and biochemists; and upper-level undergraduate and graduate students in these disciplines.
