The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems
Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.

Automation Of A Homogeneous Proximity Assay For Detection Of Residual Protein A In Biological Therapeutics
Protein A is used in affinity chromatography for therapeutic antibody purification and has been shown to leach from columns during purification of antibodies resulting in contamination. Residual Protein A in therapeutic drugs could elicit mitogenic or immunological reactions in patients.

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.

Proven Long Life Lasers™ In Optical Particle Counters Optical particle counters (OPC) utilize light illumination and extinction to determine the presence, size, number and/or concentration of particles. Particles are typically suspended in a fluid or air, which flow through the volume that is illuminated and viewed by the detection system.

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.
