The time required to completely dissolve cellulose depends on the solvent type, crystallinity and molecular weight of the cellulose. This can be 1 to 60 days.Column Eluent Flow rate Detector Column temp. : 50 ˚C: Shodex GPC KD-806M x 2: 10 mM in DMF: 1.0 mL/min: RI PolyvinylpyrrolidonesCellulosesPhenoxy resin51
