A hollow fiber membrane separator with a nominal molecular weight cutoff of 100,000 is fed a solution of proteins at the rate of 250 mL/min. The composition of the protein solution is protein A ( 4 g/L, MW = 20,000), protein B ( 7 g/L, MW = 150,000), and protein C ( 6 g/L, MW = 300,000). The filtrate flow rate is found to be 116.4 mL/min, and the flow rate of the retentate is 133.5 mL/min. The concentration of protein A in the retentate is found to be 5.84 g/L. What is the concentration of protein A in the filtrate, as well as the concentrations of proteins B and C in the filtrate and retentate?
