FFF channel dimensions (cm) 28.7 cm long ×  1.8 cm wide ×  0.021 cm thick
Sample volume (μL) 20
Delay time (s) 12
Equilibrium time (min) 2.0
Membranes 1 kDa RC, 10 kDa RC, 10 kDa PES
Carrier solutions 0.02% (v/v) FL-70 with 0.02% (w/v) NaN3, ammonium carbonate 0.25 mM
Channel flow rate (mL min−1) 1.0
Cross flow rate (mL min−1) 0.8, 0.5a
  1. aThis cross flow rate only applied in the use of 0.02% (v/v) FL-70 with 0.02% (w/v) NaN3 carrier solution with 1 kDa RC
