1st Edition
Separations Technology Pharmaceutical and Biotechnology Applications
Authored by a team of respected scientists and technologists, this book covers many pharmaceutical and biotechnology separations methods currently in use. Practical applications and descriptions are offered for air elutriation, microporous filtration, ultrafiltration, phase partitioning, crystallization, and chromatographic technologies such as adsorption, affinity, chelate, ion-exchange, size-exclusion, template, hydrophobic interaction, biotransformations, and chiral separations.
Containing hundreds of references and a complete index, this book is designed for research and development scientists, process optimization engineers, and quality control laboratory scientists as well as quality assurance professionals and others needing to understand current separation techniques.
