| Abstract: | Objective:To establish the method for determination of methylic alcohol and fusel oil in the wines by gas chromatography with programmed temperature.Methods: Programmed temperature method,HP-INNOWAX column and gas chromatography were used to determine methylic alcohol and fusel oil in wines.Results: Good linearities were obtained in all groups under this experimental condition,the relative standard deviation in the range was 1.21%~3.93%,the recovery rate was 91.5%~101%,detection limit of methylic alcohol was 0.5 ng,isobuthl alcohol was 0.2 ng,and isoamyl alcohol was 0.12 ng.Conclusion: The method had the advantages of good precision,accuracy and sensitivity,which was suitable to determine methylic alcohol and fusel oil in the wines. |
