Abstract
A method for the determination of ethanol in alcoholic beverages by high-performance liquid chromatography–flame
ionization detection (HPLC–FID) was developed. An FID system could be directly connected to an HPLC system using pure
water as a mobile phase. In a durability test using triacontylsilyl (C )-silica gel stationary phase for 96 h, no significant 30
change in the retention time of four alcohol compounds was observed. So the HPLC separation of alcoholic beverages was
carried out on the C -silica gel stationary phase. On application to the analysis of six kinds of alcoholic beverages, ethanol 30
could be determined accurately by the proposed method.
