摘要
采用高效液相色谱法建立了快速分析配制酒中苯甲酸和山梨酸的方法。最佳色谱条件为:柱温25℃,流动相体系为甲醇与0.02 mol/L乙酸铵溶液体积比20+80,流速1 mL/min。此方法快捷可靠,精密度高,适用于大量样品的快速测定。
A method for rapid determination of benzoic acid and sorbic acid content in mixed wine had been developed by use of HPLC.The optimum chromatographic conditions were summed up as follows： the column temperature was at 25 ℃,the volume ratio of methanol and 0.02 mol/L NH4Ac was 20：80,and the speed of mobile phase was 1 mL/min.Such method was suitable for rapid determination of large quantity of samples due to its simplicity,reliability and high precision.
