Preparative chromatographic separations in pharmaceutical, diagnostic, and biotechnology industries: current and future trends.

Chromatography is widely employed in industry for the purification of biotherapeutics and diagnostics. Regulatory requirements dictate that the chromatographic process be reproducible and provide the necessary product purity. Current trends in designing and implementing purification strategies take into consideration the requirements for both chromatography media and equipment. Future trends will require that cost containment is considered. New chromatography materials, new methods for equipment design analysis, and new technologies to ensure regulatory compliance will provide the biotechnology industry with tools to provide tomorrow's products.
