摘要
建立了烟用香精中乳酸的快速气相色谱分析方法。色谱柱为2m×3mm Ⅰ.d.填GDX-102的不锈钢柱,FID检测器。线性范围为0.08～2.50mg/mL,r=0.9978;平均回收率97％。该方法灵敏度高、简便、准确。
To establish a method for rapid determination of lactic acid in tobacco essence by gas chromatography. The gas chromatography column is a 2m x 3mm I .d. Stainless tube packed with GDX-102 stationary phase and the detector is FID. The result showed that the linear range of calibration curve was 0.08-2.50 mg/mL (r = 0.9978); Recovery was 97% . The method is simple, accurate and sensitive.
