Metabolite analysis in cell culture – Photometric analyzer vs membrane-based systems

Optimization of Glutamine Measurement in Cell Culture Operations Current “membrane based” instrumentation utilized at a large cell culture manufacturing site has presented recurrent problems including non-repeatable, inaccurate metabolite analysis, especially of Glutamine. These membrane / electrochemical technologies have shown inherent flaws in measurement stability and excessive maintenance at multiple sites. Newer optical-based metabolite analyzers were evaluated to […]
