摘要:

本实验采用反相高效液相色谱法实现了对乳酸、乳酸甲酯的分离并对其定量分析效果进行研究。HPLC 分析条件为:Purospher STAR C18 反相柱,二极管阵列检测器,以0.005mol/L H2SO4 与甲醇混合溶液(9:1,V/V)为流动相,流速为1.0ml/min,进样量20μl,检测波长210nm。该方法快速、简便、灵敏、重现性好。

关键词: L- 乳酸, 乳酸甲酯, 反相高效液相色谱(RP-HPLC)

Abstract:

A reversed-phase high performance liquid chromatographic (RP-HPLC) method was developed for the simultaneous determination of lactic acid and methyl lactate. The HPLC was equipped with Purospher STAR C18 reversed-phase column and diode array detector. The mobile phase was composed of 0.005 mol/L H2SO4 solution and chromatographically pure methanol (9:1, V/V) with the flow rate of 1.0 ml/min. The injection volume was 20 μl, and the detection wavelength was set as 210 nm. This method is accurate, simple, rapid and reproducible.

Key words: lactic acid, methyl lactate, reverse phase-high performance liquid chromatographic (RP-HPLC)
