White Paper: Capillary Electrophoresis — A Simple Technique
In 1989, Beckman Instruments introduced the first fully automated capillary electrophoresis instrument (P/ACE™ 2000) to the scientific community. At that time, CE demonstrated exceptional resolving of selected compounds, but the new technology lacked a track record of applications. By Beckman Coulter, Inc.

Microbial Fermentation In Single-Use Xcellerex™ XDR-50 MO Fermentor System
This application note describes the performance of a single-use Xcellerex XDR-50 bioreactor system when used in cultivations of E. coli and of modified Pseudomonas fluorecsens (P. fluorescens) producing a monoclonal antibody (MAb). Both the achieved microbe densities and product yield were shown to be consistent with the performance of conventional stainless steel systems.

A Disposable Valve For Process Chromatography
This case study discusses the need for a fully automated, disposable chromatography system which was PLC controlled and designed for use in a cGMP environment. The required applications for the chromatography system included contamination removal, and concentration and purification of biologically derived proteins used in the production of research and clinical materials.

Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers
Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.
