The dry hydrolyzed samples were dissolved into ultrapure water to make 10ml volume, eventually the sample was diluted to 10ppm for injection in HPAEC. Eluent A was ultrapure water (0.055 μScm−1 at 25 °C); eluent B contained 170mM sodium acetate (NaOAc) in 0.1M NaOH, while eluent C consisted of 0.5M NaOH. Eluent B was prepared by dissolving NaOAc in ultrapure water…
