Abstract:The ethanol in medicament was separated by capillary column, and its content was determined with using n-propanol as the internal standard. The capillary column zebron ZB-50 (30m×0.32mm×0.25m) was employed in this experiment, and the nitrogen and n-propanol was used as carrier gas and internal standard concentration, respectively. The pre-column pressure was 0.4MPa, the split ratio was 30:1, the inlet temperature was 220℃, the column temperature was 45℃, the FID detector was used at 250℃ and the injection volume was IμL. The results showed that under these conditions, the ethanol and internal standard in the Huoxiang Zhengqi solution was well separated. The linear relation was good in the range (r= 0.9995, n=7), the average recovery rate was 97.0%. This chromatography method was high column efficiency, simple and fast and reproducible.
Keywords:Huoxiang Zhengqi solution  ethanol  GC
