摘要
Abstract
An ion chromatography-direct conductivity detection method was developed for determining betaine in molasses.The chromatographic separation of betaine was achieved on a WY cation column(150 mm × 4.6 mm i.d.) using 2.0 mmol/L MSA as mobile phase at a flow rate of 1.0 mL/min.The column was set at 30 ℃.Betaine was detected using a direct conductivity detector.A good linear range of the calibration curve was achieved over the concentration of 0.5-50 mg/L(r = 0.9995) with recovery rate of 93.5%-99.7% and detection limit of 0.15 mg/L.The method was suitable for the determination of betaine and quality control for betaine extraction from molasses.关键词
