HPGPC

High performance gel permeation chromatography (HPGPC) was applied in the determination of the homogeneity and average molecular weight of the PCP-100, which was combined with a refractive index detector (RID) and a column (7.8 mm × 300 mm). After filtration through a 0.22 μm membrane, 20 μL of PCP-100 solution (0.8 mg/mL) was injected into the HPGPC system and carried out with ultrapure water at flow rate of 0.6 mL/min. The average molecular weight was calculated from a calibration curve, which was constructed by reference to T-series dextran standards (T10, T40, T70, T500, and T2000).

HPGPC

CSPs (5.0 mg) was dissolved in 1.0 mL pure water and injected into the Shodex OH pak SB-804 column (300 mm × 8.0 mm i.d.). The flow rate of the mobile phase was 0.8 mL/min. The injection volume was 20 μL. T-series dextran was used as a standard.
