摘 要:研究了快速测定葡萄酒中有机酸的高效液相色谱(HPLC)法,其最佳条件是:色谱柱Aminex HPX-87H柱(300×7.8mm),流速0.6mL/min,进样体积10μL,检测波长210nm,柱温55℃,流动相0.005mol/L硫酸溶液与去离子水配比为90:10。该方法的保留时间变异系数在0.037%~2.144%,有机酸变异系数在0.5305%~2.1559%,有机酸回收率大都在85.95%~101.66%,精确度高、重现性好。The high performance liquid chromatogram (HPLC) method for the determination of organic acids in wine was studied. The established HPLC optimal conditions were followed: Aminex HPX-87H column (300 × 7.8mm ) was used, the HPLC chromatographic separation was carried out by using 0.005mol/L sulfuric acid in ultra pure water with the ratio of 90:10, the flow-rate of the eluent was 0.6 mL/min and the column temperature was 55℃, for whole-wavelength monitoring, the detector was set at 210 nm for all acids. The established HPLC method, with reproducibility was better than 0.037% ~ 2. 144% for retention time,precision better than 0.5305% ~ 2. 1559% for organic acids and recoveries of organic acids mostly in the 85.95% ~ 101.66% range,was suitable well for the determination of organic acids in wine.
