SEC operates also in the preparative way by trapping the smaller molecules in the pores of a particles. The greater molecules basically go via the pores as These are as well big to enter the pores. Larger molecules therefore move in the column more quickly than more compact molecules: that is certainly, the smaller the molecule, the more time the r

Increasing recoveries with increased pressures in order to decrease the quantity of reject water will produce lessened permeate purity. If enhanced pressures are desired over time to realize exactly the same permeate flow, this is a sign of partial membrane blockage that needs to be corrected before it gets to be irreversibly fouled, and pricey mem
