For biopharmaceutical production, it is very important to maintain consistent chromatographic performance as well as high standards of hygiene.
This application note presents microbiological challenge tests in AxiChrom columns. Results demonstrate highly effective sanitization and cleaning with 1 M sodium hydroxide (NaOH) and reduction of endotoxin levels to concentrations below those recommended by regulatory authorities. Column efficiency testing Before starting the purification process, the preparation and qualification of packed columns are important steps to ensure robustness and safety of the column. This application note describes the theory and experimental test practices used in column efficiency testing. |
