Examples of using this product（for reference only）

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.

IC

Ion chromatography was employed to determine the monosaccharide composition of the PCP-100, and it was coupled to a column (150 mm × 3 mm) and a pulsed amperometric detector.The PCP-100 (1 mg) was hydrolyzed by adding trifluoroacetic acid (2 M, 1 mL) for 3 h at 110 ℃. Following drying under nitrogen, the hydrolysate was mixed thoroughly with methanol to completely remove the excess trifluoroacetic acid. Subsequently, the hydrolysate was diluted with ultrapure water, and the injection volume was 1 mL. The mobile phase consisted of two solvents, in which mobile phase A was sodium hydroxide and mobile phase B was sodium acetate in sodium hydroxide. The flow rate was set at 0.4 mL/min and the column temperature was set at 30 ℃.
