| Abstract: | The contents of ethyl acetate in some best-selling liquors in western Hubei, China were determined by capillary gas chromatography （CGC） with programmed temperature and FID detector. In this study, polar quartz capillary column（AT.PEG-20M 15m×0.25mm×0.331μm） was used and the internal standard was n-amyl acetate. The detection conditions were as follows： the initial column temperature was 60℃ and kept for lmin; and then the temperature was increased to 150℃ at a rate of 3.5℃/min, maintained at 150℃ for 5min; the temperature of injection port was 170℃; and the temperature of FID detector was 170℃. The standard recovery of ethyl acetate reached 99.41% by this method. The method was fast, accurate and sensitive, and could be widely used for determination of ethyl acetate in liquors. |
