Next, calculate the range of the data set by deducting the minimum value from the maximum value. Next, determine how much more in value ...
Webcellulose membrane. Stable process pressures and flow conditions indicate absence of plugging and suitability of cassette design. No Protein Loss Samples of composite permeate from each process run were analyzed for protein using the biuret method. No protein loss was detected in the permeate, indicating greater than 99.9% protein yield.
