Foaming during ufdf
WebTo ensure that the installed membranes have not sustained damage during storage and handling, MilliporeSigma recommends air integrity testing all TFF assemblies pre- and post- use. An air diffusion test identifies such problems as macroscopic holes in the membrane, cracks in the seals or improperly seated modules. WebDuring the process simulation, collect the following data: Monitor flows and pressures and retention. Collect samples of all initial and final streams. Calculate process time to ensure that it is within the expected range. Test the quality of the final product with reliable assays. Calculate not only the yield, but also mass balance.
