Sample Requirements "Citrate analysis"

Methods are established for “state-of-the-art” chemically defined cell culture media. Due to potential matrix effects verification of sample feasibility might be necessary prior to analysis. Please note that feed media matrix should be considered seperately. If you plan to measure pure feed media, feel free to contact us for more information.

Please read and sign our sample declaration sheet and prepare and ship your samples according to our sample preparation protocol.
