ABSTRACT
Objective:
To establish a detection method for ethanol in HuaiShi province Ye.Methods:
Ethanol in HuaiShi Ye was determined by GC with a DB-ALC1 capillary column(30 m × 0. 53 mm,3. 0 μm), an FID detector and nitrogen as the carrier gas. The injector temperature was 200℃, the detector temperature was 250℃ and the column temperature was 80℃. The flow rate of N2 was 5 ml·min-1 . Tertbutyl alcohol was used as the internal standard, and 1. 0μl sample was injected by a headspace injector.Results:
The solvents were completely separated, and the calibration curve of ethanol had good linear relationship within the range of 3. 177 0-15. 885 0 mg(r=0. 999 6), and the recovery was 98. 7%. The intra-day precision of different concentrations was less than 2. 5%.Conclusion:
The method is sensitive, rapid, accurate and reliable, and can be used for the determination of ethanol in HuaiShi Ye.
