The conditions such as applied potential, composition and flow rate of eluents for determination of carbohydrates, including glucose, fructose, lactose, sucrose, raffinose and matos, by gradient elution ion chromatography are discussed. Two different eluenst, eluent A(1mol/L NaOH) and eluent B(0.15mol/L NaOH), and a gold electrode pulsed amperometric detector are used. Carbohydrates in wine and tangerines are analyzed. The results show that the gradient elution is more sensitive and needs shorter time than isocratic...
