| Abstract: | A method was established to determine glucose and fructose in wine by using ion exchange chromatography with pulsed amperometric detector.The samples were separated on a CarboPac？PA10（4 mm×250 mm） anion exchange column using gradient elution of sodium hydroxide,and the velocity was 0.8 mL/min.The detection limit of the method was 0.1 mg/L.The relative standard deviation of this method is 3.2%~5.6%（n=6）and the recovery is the range of 93.2%~104.5%.The method is accurate and simple,and is suitable for rapid detection glucose and fructose in wine. |
